Split this into multiple posts because of character limit.

1. I read that I should just throw every attribute point into Mind, but was told today that I am bad and should be throwing 1 into piety and Vit for every 5 Mind... Is this true? Have not seen anything that regards this situation.
I would suggest all into MND because of one key aspect of WHM. Your job is to be the burst/tank healer in a group in late game. You want your healing potency to be at its peak. Determination and MND allow you to do this as well has a weapon with decent damage since that factors into the equation as well. PIE doesn't matter as much since you should be using shroud for refresh as well as aggro management. Vit doesn't help nearly as much as you'd think it would since what little bonus you get isnt enough to really mitigate anything. You should be trying to avoid as much damage as possible.
