I'm happy of my 30 vit on all jobs and cannot count how many times that saved the day.

Ho yes if you put points into the 'right' stat you higher your dps, but every time I'm told this, I will think that a dead dps does not dps, and a dead healer doesn't heal.

Take account all the above, is because I will PUG often so it is a necessity. If you are with a static and confident you will not be pushed over your HP low limits, well yeah, take that points where they belongs
