This list will cover BiS paladin healer list for all raid tiers. Some items will be skipped, as others from lower tiers are superior and easy to obtain.
Most of the items are ranked by the standardized formula:
1heal = 1heal
1int = 1heal
1%crit = 12 heal
1m5p = 3 heal
Under each item, there will be a final number of "+heal" which item roughly provides.
I would like to underline the fact, that formula presented above might be inacurate, or different according to current tier progression/playstyle/boss fight, and even custom private server scripts.
It is not an aim of this thread, to go through endless number calculations to get exact stat values. Aim of this thread is to present complex list of viable holy paladin items for each slot through all vanilla tiers and offer a basic overview on item superiority.
