ok is a lot here for me to wrap my head around so let me try to break this down...
Once again, you're a fountain of uo knowledge. Thanks for taking the time to be thorough with the build and tactics. The human makes perfect sense to run for a pvp toon.
Im currently finishing the suit for this current build.... shes mainly for pvm peerless and spawns, but might fare ok in pvp with some suit/stoned-skill adjustments (although id run a dif template for serious pvp)...who knows. the 700 cap calls for some serious cramming to get all these skills in...but here it is.
Elf
110 tame
110 Lore +5 (115)
85 +15 Necro +5 from tali and jewels (105)
95 SS +10 from tali + 15 jewels (120)
115 weave
85 mage +15 Tome (100) **for gates, res, heals, cures, etc
100 vet
stoned skills to swap for vet:

+ 5 lore
+15 ss

head ??? Kasa/magi? runic?
The idea is to cram as much MR on the suit as I can (also in wraith 90% of time anyway). But I also have med, eval and resist stoned for off for this char to swap vet out for (since this is mainly a pvm planned char). I also have a little bit of cushion left on those jewels. This template is very fun to play and super effective at spawns, doom, peerless etc....although the sdi should be higher :/
I used to run a template similar to this for soloing lady mel, I dropped vet tho and picked up eval so that I could do damage threw magery and leech mana back. I ran very little meditation, if any because of the mana leech. A super slayer book does 2x damage to mobs, and a single slayer (example dragon slayer) does 3x damage. With these changes it is possible to do a huge amount of damage, and so you can leech back enough mana to basically keep going non stop. Word of Death doesn't use slayers, but you leech threw wraith, which allows you to cast it non stop...assuming you are fighting a high mana moster. Lady Mel is a fey slayer, and the new boss in SA, stygian dragon, regulary drops a fey slayer mystic book. Anyway with spellweaving you can pretty much negate vet, you can use a "dot" heal known as gift of renewel and you also get arcane empowerment, which increases the amount of damage healed letting you heal your pet back up quickly. On top of that you can cast a spell called gift of life, which is a self res, but it is castable on pets also. It is not a sure bet, and you have to keep recasting every so often, but it is nice to know you have the ability to res a pet if need be. In all honesty tho with arcane empowerment g heals your pet shouldn't die.
I should mention that with this template you really need to run a Greater Dragon, the high hit points mixed with great resists really makes for the best tank in game...and you are relying on wraith form so you will be on foot anyway...it just makes sense.
As for the suit, Lower Mana Cost is important so that you can reduce your cost of casting spells. Most people think MR beats LMC, but this isn't true. You could have 20 MR and 10 LMC and will constantly be out of mana because spells take a larger chunk of it to cast. LMC works by 5s, so having 28 LMC for example is the same as having 25. Anyway if you can get this to 35-40 you will be in good shape. With wraith form you should leech enough mana to be ok anyways..assuming you have eval. Kasa of Rajin is a great resistance piece, but it lacks mods. Hat of Magi is nice for the 4MR and 8 int bonus but has low resistances. I would just try to do the best you can, if something doesn't seem to work very well swap it out and try something else. Usually tho a kasa is used in conjunction with a pendant of magi since the pendant is high on mods but low on resists.
for pvp, I could lower weaving a bit and swap out vet which would give me some flexibility for eval etc.
Pvp tamers do not run vet usually. Greaters can be killed easier then I care to admit, hailstorm with dragon books is crazy damage.. but the firepower is huge compared to most templates. Your average dexxer is not going to want to stand toe to toe with a Greater, and if you cast on top of it he isn't going to be around very long. A smart mage will try to paralyze your dragon, or invis a lot to get it off him, but that is why you use your magery/necro/spellweaving. Also if you say "All Guard Me" if you are targetted or if you do damage to someone the pet will go for that person, this makes it very important to say "All Guard Me" when withering, your pet will chomp multiple people as you wither, potentially killing everyone around you, in the very least making them scatter. HOWEVER, if you plan to pvp you really need 120 skills, GM or 110 will work for pvm, but you it will hurt you in pvp. For example mysticism is directly based skill vs resist spell. Almost every character that has resist spell is going to be 120, making 120 mysticism very important. Spiritspeak can be run at gm or 110, but the big damage, and the big curse durations will be at 120 ss. Also do not ever underestimate spellweaving, 90ish skill is 100% to cast essence of wind which is the biggest enemy of a mage in game. It will literally add seconds to casting time, if a guy is 'winded' and trying to cast mass dispel for example he may not be moving for 10 seconds. This gives your pet a great target to chomp. Just make sure you get a level 6 arcane focus, this literally adds 6 seconds to debuffs (wind, t-storm, etc), damage to spells, duration and points absorbed or healed(attunement/GoR). The biggest thing you need to worry about in pvp is the defense. Most tamers are weak on defense which leads to the kill the tamer idea vs killing the pet. If you can make it so your tamer is hard to kill, you will kill a lot of people. An archer for example could run around non stop, using the moving shot special and kill you before your pet ever gets close to them. A mage weapon is the best bet, it's free defense as long as you have it in your hand (watch out for disarms).
A few other fun pvp templates I had an idea of trying out were these:
myst archer tamer
myst 110
focus 100 (120)
arch 100 (120)
tact 90
tame 110
lore 115
chiv 75
Try to fare with the 4/6 chiv casting for heals/remove curse etc....pretty much use myst for spell plague spam and healing stone while casting pets nuke and you follow with mortal/para shots. stats and suit might be an issue tho...but i think it could be fun! remove curse, close wounds, cleanse by fire on 4/6 + trap box ftw
The problem here is that mysticism is just like magery for chiv. You are capped at 2/6 chiv when you go above 59.9 magery or mysticism. (My numbers mayb off a little, it could be 49.9 I forget now honestly!). But the point is the same, you can't be a 4/6 chiv mage or mystic

. The mystic archer was nasty with a Yumi bow, double shot and spell plauge was pretty much insta killing people. It is something to consider but it seems more like a yew gate template to me. Also without resist spells you are limited to what you can do. If you get mana vampired you are pretty much a sitting duck since almost all of your healing is threw mana. 4/6 chiv without resist is easy to kill, 4/6 chiv with resist is very hard to kill.
Ninja wrestler stealth tamer
110 + 10 wrestle (120) from pugs
120 ninja
85 +25 Tame (110)
110 Lore
110 Stealth
100 Hiding
65 Chiv
So Gimp, it'll make you wanna slap someone's momma
Would need uber dex.....but id run with plenty of bolas and a GD. Disarms, stuns, death strikes (they WILL run), all kills, darts, smokebombs, 4/6 chiv....you get the picture

This template would be seriously LULZ to play....plus I love the poop your pants factor of a stealth tamer ^.^
It is an interesting idea, I don't care for a stealth tamer, but it has potential for sure! I love wrestle for bolas, but I do not like wrestle for offense. The only temp I have seen that works well with wrestle is throwing/archery. The high dex gives fast swings and high HCI gives better % to hitting..but it is used mostly to counter the biggest weakness of an archer/thrower which is disarms. I don't want to say it won't work but I wouldn't try it.. I don't do stealth so that alone makes it not fun to me, but that doesn't mean it wouldn't work. Try it out and let us know!
