Well, the reason I wanted to remove this feaure is based on my personal perception of realism. I know it's a game, so absolute realism is not possible, or even desirable. I just want to be given the illusion of realism whenever possible. That's why I find it odd that vitality doesn't regenerate after a fight, but health does. The opposite would have made more sense to me.
But I'm nitpicking here! Since this part of the game is hard coded, nothing can be done to change it, and that's fine. It' s not such a big deal anyway. I' m really enjoying the game all the same.
Thanks a lot Ess-Eschas for taking the time to answer me and thanks for the suggestions! I'll up the difficulty (playing on normal currently) and see how it goes.
