Movement skill, clear skill, oh shit skill, kinda tough pack that lets me setup skill(i.e. harby packs), and boss cooldown skill.
Please, no more. Warcries, marks, totems for melee, various vaal skills, etc. PoE's speed does not support this complexity. I think Alkaizer mentioned it in one of his recent videos that you're supposed to beat the game with a properly planned build and then playing the game is just executing it. He was specifically complaining about the phasing and complexity in recent encounter design, but I think the overall idea applies here as well.
Anyway, no more easy power charge generation for most ascendancies. Indirect buff for Assassins.
