you do not want the DM to ask you every time a reaction is possible.
Yeah, actually, I do. That's what they're for - to tactically chose what and whether to use different things at opportune moments, usually outside of your own turn.
You do not want to create a situation where you give players game stopping popups when one of the answers is DO NOTHING. This one of the worst design mistakes, because humans just doesn't have the capacity to endlessly respond to the same and enjoy it.
Actually, you do... because doing nothing sometimes is the essence of tactical decision-making. You want to be able to say "no, I don't want to use this ability *yet* - I could use it now, but I don't want to, not on this 2hp goblin." The ONLY way the game can get that information is by asking you.... otherwise it's making the decision for you, often the wrong one, or something you didn't want, and is cutting you out of tactical decision-making in the process.
To be frank, combat in BG3 has pushed the line of feeling repetitively mind-numbing and dull far more than any situation I've dealt with in Solasta so far, and the latter game shows that reactions can be handled smoothly, and in a way that is acceptably fluid and which doesn't interrupt combat flow in any notable way - have you played this game? What was your experience of it?
