I was wondering about druids Healing Touch spell. You've set casting time to 3.5secs which isn't true when taking talents (= -0.5 sec) and ranks in account. I see you've added some talentInfo but just checking up :-)
Anyway, here's the data for every Healing Touch spell rank 1 trough 13: http://pastebin.com/850182
+healing affects take into account the untalented cast time so for the purposes of calculation, 3.5 seconds is correct.
