Only annoyance there for me has always been CHs. Even a few months ago, i would still have them get off more CHs than I was happy with, even with pet popping out irionu and epic stuns.
Edit:
Slight shift, but just wanted to brag a lil. Felt sorta cool to solo a WoS ukun yesterday. Reason its an accomplishment is that i tried to pull it back down the hill where I agro'd it (i was otw to anguish & tried the wrong way there ;p) and was on wrong key pad.. so pet got et before I even started working it. Was totally unbuffed for half the fight, till I relaxed & remembered potions. Clicked the hps (which did save me ;p) and the ft. FINALLY landed slow at abt 50%. Threw everything had at em too ;p Killed the sob, me like 20%, under 1m, unhasted and unbuffed except my 36% from aug, potions & time cloak ds clicky. Felt sorta cool.
