Priest vs Mystic–a comparison guide

Hey everyone, TERA North America Closed Beta 2 (CB2) drawn a close this weekend and I was fortunate enough to have time to level both a priest and mystic to the level cap for CB2 (level 27). I will give you some of my personal perspectives on the two healing classes in TERA up to level 27 and also some comparisons of the later abilities available for each class.
