Mmm, I suppose that the easiest way to compromise would be to just remove the concept of HP. So people who want to specify how much damage they do in relation to their stats can do so, and people who just don't want to do that can do so, and it'll have no real bearing on whether or not how quickly someone should die.

Using the Kobold Lord as an example...the dude only had around 7000 HP, but was being bombarded by Sam for around 600 damage per shot, not including all the damage that's been done with Ren's arrow spam too. It shouldn't have been a fight at all, from my point of view. If you simply removed HP as a marker though, that'd basically be fine, because then, there's no way to prove mathematically that something should be dead before, y'know, they do anything at all. I'd argue the same for MP too, really, cause there's no real point in tracking it.
