I am not talking about cinematic, I know I can attack and even move by coordinating movement with the mini map, I do that as well.
I talk about the two (or one) spacebar-smash bar "mech" phases, my unmodified client get's all abilities greyed out. After I am unable to attack I still see Koldrak HP bar for a bit mostly around 100-200Mio HP and often has almost no more dmg incoming. As said all my abilities are already greyed out for a bit at that point and I already been ported to one spot as everyone else.
Then the Space bar smash starts and next time I see anything from Koldrak it's his death animation. And I do at least 3-4x runs with my toons and right when I seen the banning post in forum, the Koldrak kills been back to normal for 3 days. Btw. if someone has the chance to do so, you think he leaves loot behind for fair-play?
Waiting for your educated response.
PS: funny enough, I just did another 3 Koldrak runs to check, all at normal, 2 kills within cinematic, sadly not by me.
