If you as the healer die, the whole party is screwed. Vit helps keep that from happening. If you know the fights and everyone does what they are supposed to, you won't need extra vitality, but that does not always happen. I have a full set of melded accessories that gives me a lot of extra vitality and it has saved plenty of runs. That said, I currently have all 30 points in Mind. My jewelry gives me plenty of extra Vit. I agree Int is a waste and PIE is not the best use for your points. At low levels, Vit and PIE do make a bigger difference than they do in endgame.
