Really? I hear this all the time. But it doesn't make much difference on my main stat in my ability to heal people. I put most of mine in Vitality. I find it is easier to manage MP if I have more health myself, because in the burst attacks I can focus on other people first and have a much better chance of keeping everyone alive, and usually by the time I have brought everyone else back up, I have a free cure to throw on myself anyway.

If this changes later in game, I can just use seals to buy the reset. So.. I disagree! It lets you customize potentially based on where you are in the game, and what your needs are, and your own personal skill level/play style.
