The mere existence of VATS as a in game world Spell is one of the worst things Bethesda did. Focusing on it more would just make the game worse. I'll say if it now has to have real time combat is better for it to be good real time combat and for VATS to be fully replaced with something else, maybe a Bullet time effect where you get to target parts more easily and for the Body part damage system to return (FO4 basically made it moot) and for there to be more focus on Melee and unarmed too. Also make more than 1 minigame for hacking and lockpicking. Why do all doors have the same lock? Why not make it so that the Lockpicking and hacking skills aren't just keys to unlock arbitrary "levels" of the same minigame but they would also allow you to bypass them by crafting tools and shit?
