up until level 25 or so i found the melee healer to be pretty balanced with no real health/mana problems, but i've now started to lay into his real path where i'm low on mana from just 4-5 fights. thus forcing me to use the prayer skill for mana regeneration and topping up. Granted Every level skill point i've point into wisdom with the exception of a few points in to luck.

This is my spec so far:
