I wonder if speeding up some animations to fit within a time frame would look really janky or not. It's a possible solution but not if it looks like fast forwarding a VHS.
To the OP:
As for channeled abilities, there are more than just Collective Unconcious (see: Flamethrower, Improvisation, Meditate, Anatman, Passage of Arms). Even though they look cool, I kind of hate them. I don't like clicking an action and then doing nothing while my ability plays out. I don't like having them be interrupted by the need to move out of AoEs because that feels bad and like a wasted ability use. The downtime abilities/mitigation work well for that purpose but otherwise all feel bad to use in combat. The one true channel, Flamethrower, is even worse the longer you use it. Just doesn't feel like a good system in this game.
