Its defiantely not performance based as Ive had it happen while running at 60fps. The entire bar simply refuses to activate skills and hotkeys wont work. I can still move, chat, dodge and use the TP but I simply cannot use any skills under any circumstances. Respawning, downing and res’ing, and reloging all have sofar “cured” the condition once it hits but the fact it happens in the first place is the problem.
I also start to have this problem since a week ago, and what’s worse, even when I am totally alone, the lag happens. PC performance is out of the question on me, too.
