I would appreciate an ability to skip animations/accelerating combat dynamically - the game already plays too fast for my taste, with NPC doing their moves before the camara manages to pan over to them. I would prefer a cleaner, default experience with an ability to speed it up.
In general "skipping animations" or "moving in fast forward" may be useful options to have, and I know that in every tactical turn-based game ever made there's always a subset of "extremists" who would give up on ANY type of eye candy only to erode away few fractions of seconds.
Personally? I enjoy having something that looks good, so I'm not that far into "optimization".
What I'd advocate for on the other hand (aside for the obvious speed-up of the AI planning that I'm sure developers are already pushing as far as their capabilities allow for) is try to make things as "snappy" as possible in general.
For instance the Barbarian berserker animation could remain fundamentally unchanged in its visual appeal but just made few fractions of seconds shorter, the "Dash" could do without the 1-second-wasting Supersayan-inspired power-up, the jump could feel a bit more "smooth" and agile and less "stompy" and so on.
In some games I noticed that sometimes it's not even a matter how much time an animation takes, in general, as much as how quick it is to start or to give back control to the player after finished. Basically how responsive it feels.
