I don't have either class but idk if it was Taliesin's settings or just the BFA version of em but both classes are piquing my interest now, even disc and holy specs for priest too (after watching the Healers video).
I think BfA is going to be the expansion where I bring up many alts @_@ I'm actually intentionally waiting for pre-patch before leveling up a warrior and hunter for instance (2 classes I always thought were boring as fuck and never touched ever since I began WoW in 2010).
