Hi
ICP is impossible to do. Huge lag spikes (ping 700+ sometimes - not internet problem), ability doesn't damage, healing doesn't work, tank taunt mobs and they "dance" (this happens in all dungeons) , etc etc
And to help the final boss it is full of bugs.
When it flies, no longer appears, or if it does, it is impossible to damage it - in HM or EM.
2 hours doing a buggy dungeon with lag, so in the end not to kill the final boss.
