PvP Stealth archer(assuming scroll availability):
120 archery
120 tactics
120 Stealth (use items for bonus skill points, shadowdancer leggings, etc)
120 ninjitsu
100 hiding
... As you can see, healing is a big problem at this point, as a veteran account has only 140 points to spare for healing. You can counter this by going with alchemy (EP from skills), or lowering other skills to fit in healing/anatomy (90 each is good).
Your primary goal in the field is dismounting and specials, so get a fast heavy crossbow and a good bow (mortal strike/paralyze) and a yumi (double shot after someone else disarms your victim). 95% of the time, you'll be using the crossbow.
Smoke bombs will be your best friend with this template. I used it myself for a while, but gave it up for a mystic/warrior... it was very fun in Felucca, less so in role-play.
Bushido/archer:
120 archery
120 bushido
120 resist spells
100 tactics
100 healing
100 anatomy
60 chivalry
The bushido lets you use the yumi, which gives the best possible burst damage in PvP outside of a mystic/warrior's spell plague abuse. It also gives you confidence for healing and lightning strike for cheap burst damage. The bushido/archery combination also gives you cheaper special moves. Aneirin's variant uses 100 meditation instead of 120 resisting spells, which gives me more specials. It's great in groups, less so in duels (especially against mages).
Now, Aneirin dropped bushido for mace fighting, which gives him the double whammy of disarm and armor ignore for finishing many fights quickly. The faster melee weapons are also great for interrupting mages.
Plain-Jane archer:
120 archery
120 tactics
120 healing
120 anatomy
120 resist
60 chivalry
60 meditation
Hits like a truck, great for crossbows and heavy crossbows. Weapon specials are costly, so be conservative (my ex-faction archer had this template).
For ship-to-ship fighting, I HIGHLY recommend an alchemy variation of one of the above template to toss explosion potions for best results. Be sure to include 50% enhance potions on your suit.
