Agree, in RTWP reactions would have to be a toggle ON/OFF that auto trigger. In TB... oh wait...
A faithful 5e game would have a hard time with RTwP due to all the reactions which many classes rely upon. But the way BG3 is built I don’t see why it can’t be done. I mean there’s no meaningful reaction system in the game.
I personally don’t care. But with the current state of the game, RTwP is quite feasible. It won’t change though. Like many other requests, Larian will ignore if it doesn’t align with whatever vision they have of the game.
