Right. But that's not good. It is like a cheat. My party locks an enemy I'm combat and I can roam the whole map, sneak around behind them, and so forth without triggering combat? Here's a cheat strat. Send a familiar to trigger combat and leave it there. Then sneak around and do whatever you want because that enemy is frozen in time. Ah, a new familiar magic never before heard of; the ability to freeze enemies in time. 😁
Honestly, I think this is as good an argument as one could make for RTWP. once you've got some characters in turn based because of combat or dialog, and others free to roam, your system probably isn't working as intended
