I was having a hard time with agro in Kael last night.. i will try to explain situation thoroughly so people can point out if there's something obvious I may have missed, so sorry if this is a bit long.
I play a 70 ROG (~60AA, 1.5 Epic, backstab maxes at about 8000 with daggerfall), and I usually play with my own paladin bot in Kael, he holds agro no prob. Last night, grouped with guildie boxing Mage (pally bot, lots of AAs), Cleric, Necro (also high AA). Waited until Mage sent in paladin bot (he usually sent his pets first, which knocked most giants down to 85% or more in no time), then I would attack once paladin bot had engaged. EVERY TIME i attacked, I would immediately pull agro from the group, despite not leading with a backstab. At one point, I hit twice once for 9dmg, once for 45dmg and had taken agro right away. Paladin bot/Casters were unable to pull agro back despite me being unable to backstab (since i was facing mob now) and near-constant evade. I died twice in span of about 10 minutes doing this.
At this point, I got 96 CLR res, while waiting for res effects to clear, we recruited 70 SK to tank for us since I was basically unable to engage any mob, no matter what health.
Engaged two Sentinel of Zek, Mage/Necro/Pally bot had mobs down to about 45% before SK engaged (I think he was not paying attention ha ha), I ran in shortly after SK, and instantly (without even attacking) had both mobs agroed on me, beating me to a pulp.
I have never experienced anything like this before, during this past week I have played in Kael, PoV, SSRA, ToV, PoFire. I died about 5 times in about 30 minutes, and logged for the night, so I did not get a chance to check to see if it was occuring in other zones.
Any help here would be great! Thanks!
