If you think back to when staff buffing was fixed, when we only had crafteds and not everyone had bezes (and there were no ralers), it was almost balanced.

However the stat inflation started going out of control which showed up the flaws in blunt mastery (and proved what I was saying about the equation being written and only suitable for the previous meta) along with dekans throwing around their 1-hit phalluses.

You have to start using the old "why?" trick to find your solutions:
Templars have access to too much attack power. Why? Because the blunt mastery formula was written for a previous meta where there wasn't such stat inflation.
Templars claim this attack power is currently necessary. Why? Because it would otherwise be impossible to kill vitties.
It's impossible to kill vitties. Why? There's too much vit/HP out there along with insane pots which are easy to obtain.

You start at the end and work your way back. Fix the healing issue > look at changing how vit/HP works by potentially reducing the vit to HP bonus (also helps with dem pesky wizzords) > reduce templar melee > apply additional fixes (D/W FFS, wiz reraise etc.) > happy peoples.
