unless you have NO control over the reaction, the combat is going to be slowed down by a player controlled reaction system. Go ahead and show me how a 2 minute long fight would be shortened by adding in more player input.
I don't about yourself, but I play games, to play them. Better, tighter control over character's action and allowing for decision-making during enemy turn, does sound more interesting then sitting through a turn and fiddling with toggles (granted I didn't see many reactions available in BG3 EA). Combat encounter might take more time, if it constantly interested. And enemy turn still being "your turn" is more interesting the pressing "end turn" and waiting to be in control again.
At the moment reaction barely exist - which is a shame.
