And I'm not asking to change the combat in game. I ask about optional RTwP/Turn based like in Pillars, Pathfinder... Arcanum I'm not going to steal anything from you - if you want it you never change that option from "Turn based". But I want to play BG like I used to and how I like it.
Pray tell, how does one enact an action, bonus action, reaction, and free action system and translate that to real time?
Forget about those, how do we get legendary actions in ? They are the monster only actions, they take BETWEEN the turns of other combatants in addition to their regular actions. And among them, there are actions that allow the enemies to move without provoking AoOs, or even fly around.
