I do not run any leech on my ranged melee just because, its cut back by 50% But I do run more with hit spec's . My tought on this is simple.
Then lets say, I hit you with HML. If you hit your target for 50 damage with a 60% Hit Mana Leech weapon, you have a chance of recovering between 0 (50 * 40% * 1% = 0.2) and 12 (50 * 40% * 60%) mana. Not a good trade off IMO.
HLL is bout the same, If you hit your target for 50 damage with a 60% Hit Life Leech weapon, you have a chance of healing between 0 (50 * 30% * 1% = 0.15) and 9 (50 * 30% * 60%) hit points. Again not a good enuff trade off to use.
The hit spec's are 100% when they hit. So they(mages) run 70dci, do I run 50HLD or not? Nope I wont anymore cuz they are still at cap. I'll use more hit spec's . Dexxers are bout the same, but I do run with 50HLA. Now again if Im fighting a archer I'll check out the toons gear before attcking them just to see what wep I need to use so I can get the most outa my wep. Range melee has it better then melee because they can counter both HLD\HLA with imbued DCI\HCI 20\25. My Faction dismount tamer runs with a imbued HXB HCI\DCI 20 so when Im in the battle field Im at HCI\DCI 70.
The only leech IMO, that is any good in PvP is HSL. Has a percentage chance on each hit to convert 100% of the damage inflicted on the target into stamina for the wielder.
If you hit your target for 50 damage, you have a chance of regaining 50 stamina. Now again this is true only for melee not so good for ranged melee.
So for a ranged melee wep I'll imbue it like this, Comp Bow- Velocity 50.Balanced, DCI\HCI 20 and DI 10 or so, Velocity is,
physical damage is added for each tile between the attacker and the target when the arrow strikes (#tiles x3 - max 30 points), if the property is triggered. .
Ok I guess its time for me to grab a monster. I need to wake-up. Just getting kids off to school. Im gonna check this post out again cuz Im sure there are gonna be a few other posting on this. I hope this helps out.
