I'm having this problem:
In fights, it occurs regulary for some seconds, that i can't activate/use skills on my action bar and i can't (light/heavy) attack either. And it happens after i used ecplise (totally dark), and this debuff is still active on a mob. If eclipse is not present, i have only the "lag" problems as anyone else.
It seems, it happens when the eclipsed mob is casting a channeling spell against me, which puts me into this freezed state. Like some of these bats, who charges an electric shock. ... but then, i'm also locked out by necromancers, pyromages, and so on.
A collegue guessed a silence spell, but there is no area effect, and (thanks to addons.....) no visuable debuff. (And here i have to say: why are there de/buffs in the game, when it's nearly impossible to keep watch/track them?
I also thought addons might be the problem, primarely loot-aadons. But turning on/off, made no change...
