Big time NO. NO NO NO. I do not want to be clicking reactions every time the enemy tries to do something. I caved and bought solasta for 60% off, and one of the things that is constantly pissing me off is “react to this”. It should be defaulted.
I am playing to have fun, not playing a clicking simulator.
You would not be clicking reactions every time the enemy tries to do something; that's an exaggeration. Maybe, if you choose an incredibly-reaction dependent team (and you set all of your reactions to "prompt me" instead of "off" or hopefully "toggle" is still in the game), you'd use 2-3 reactions per round. And that'd be on the high end of things. Reactions only happen when a trigger occurs (barring a few omni-activateable abilities that *should* be modified for game use), which won't be every single enemy turn, let alone action. Then, using your reaction...uses up your reaction. Thus that character wouldn't be prompted any more until after their next turn.
When playing Solasta, in your party did you have a Paladin and/or someone with Protection Fighting Style and/or a Sorcerer with metamagic? If any of the above, then you probably got a much higher number of prompts than I think you should ideally/typically get in BG3. (I think Paladin smites should be a toggle; you can always choose something other than Protection Fighting Style; and metamagic should also be an icon instead of a prompt).
For the abilities that are usable after ~any roll, I agree that they should be modified. But the other things like AoO, counterspell, hellish rebuke...they really either need to be prompts or overhauled for Larian's automatic reaction system.
