I personally dislike this mentality that the freedom to choose how you play the game somehow breaks it. As others have said, if you don't like it, you aren't forced to do it.

With that said, I don't think having some cost associated with it would necessarily be a bad thing, but I don't feel it, or really anything else that grant the player the freedom to play as they wish needs to be moderated.

That was actually one of the things I disliked about the enhanced edition, and their decision to rework a lot of the skills as well as the elemental resistances. In a world where you essentially play as a walking god, and every other NPC as complete immunity to some element, you can't? That makes no sense.

I'm quite capable of moderating my own gameplay. It's an rpg, not an e-sports title.
