But im not quite sure if i want to see it with curent reactions ...
I mean, if Larian implements "ready" action as "set your target and cast when and only WHEN target will get to range" ... it would be kinda fine, to keep it automatic ... but if they implement is as "ready your spell and cast when ANY hostile target gets in range" ... that would be a new source of huge frustration. :-/
Hopefully BG3 would allow both possibilities: ready an action for when any enemy gets within range, or ready an action for when a specific enemy gets in range. Though if they somehow have to choose one, I'd prefer the former more general option. It'd be less frustrating to waste a readied attack on the wrong enemy than to not use your readied action at all because specific enemy didn't do X.
