The Hidden Forest

I've noticed that my lifetap weapon augs (such as Kiss of Life) generate aoe hate, is this intentional?

For example:
I drag a handful of npc's back to my group and I start attacking my main target building up hate. My group assists me on my target and my rogue's Kiss of Life goes off. It is extremely common for one or more npc's to peal off of my tank and attack the rogue.

The healed amount is negligible, but it's obviously more hate than I generated on my warrior by just running by and proximity aggroing the npc so it causes npcs to attack my rogue. My rogue is very squishy. A few npc's beating on my warrior may not cause me to break a sweat but a few beating on my rogue could 1 round him depending on what zone I'm in.

I realize I could use abilities like Chaos Cry to help with this but I'm just wanting to know if the heal aggro was intentional. I try to use Chaos Cry reservedly in case I get adds, the reuse timer is too long to save my groups butt if I just button mash it constantly.

I can only speculate on the intention, but I can explain why the aoe hate occurs:

Most lifetap procs on THF aren't lifetaps at all. They are nukes with a heal recourse. Insofar as I understand it, all heal spells produce aoe aggro. True lifetaps, on the other hand, generate aggro for the one target they are cast upon.

As far as I can tell, there is no aggro associated with the heal portion of a true lifetap. Pulling a fresh group of mobs and firing off a lifetap on my necro seems to build hate on only the mob I cast the spell on.

How can you save your rogue? Try to load up your warrior with lifetap and rune procs, or reduce the lifetap proc augs on your rogue until your warrior gets some better weapon procs.

P.S. I struggled with this for a long time on my warrior. The best remedy was doing the solo/raid aura quests to get the rune proc. Changed everything for me.

This is true, the aura of the Wall, and even more so Aura of the Stronghold will vastly improve hate generation for your tank.

Yeah I've had the wall aura for a while now, but I dont like relying on the rng for saving my bacon. Once my warrior gets sufficiently geared in a particular zone (currently tov for me), I am able to pull a bunch of mobs at once instead of just one. This situation is where half of my group that has lifetap weapons draw aggro if I'm not successful in hitting all my mobs with cyclone blade.

Once those 3 toons engage and proc, they draw aggro, this is nearly every pull for me now. I'm being lazy I guess, I could just stand there in one place and let all mobs gather up and pound on me for a few seconds to make sure that I hit them all with cyclone blade first. This presents it's own set of problems though, my tank dropping means a wipe for me

Heck now that I think about it, I cant be sure it is lifetap procs causing the heal hate, it could be aura of the frenzy heals.

well, one thing is that as you progress in the tiers your tank will get better and better at holding agro via weapon upgrades with more dmg and more aug slots and also from clicky items with hate procs. Still low at the tiers tank agro still has to be managed via controlled dmg since you dont have as many hate tools as you do later. The same can be said for a lot of other raid mechanics as well, such as curing for example.
