I still can't understand why any self respecting holy pally would ever think that they need mp5.
I heal 25 and 10 man hardmodes and ToGC. Mana is only ever an issue when the shit hits the fan and I end up spamming HL for relatively long spans of time.
And if I happen to be in melee range of something one attack will replenish more mana through seal of wisdom than all the mp5 on all my gear added up.
Stacking more spell power is only useful for FoL builds and other than that will only yield more over healing.
The paladin soft cap for haste is 680, which is pretty easy to get to in t9 gear. But honestly you're not going to notice a huge difference between having 500 haste and 680 in MOST scenarios.
So again I ask, HOW IS CRIT OUR WORST STAT? HOW HOW HOW HOW?
