You talk about instant heals being important and then you enchant haste. Wasted enchant especially if you're stacking crit. Improper itemization.
Any other questions?
If you do the math +16sp = +10 more healing done on your instant cast. Not nearly as important as the +10 haste.
Any other questions?
Yes. How does haste effect instant cast spells?
Globals, brah. But yes, Ore, is a douche.
