Finally got to test everything out last night. I'm really liking the little streams of water that zip through the air. I think it looks great. My only concern is with the casting animations and the low visibility Healing Rain. I'm sure I'll get used to the animations over time, but I hope that the HR is patched because it is definitely much harder to see.
They might be pretty, but the new Healing Rain is absolutely horrible in terms of visibility in raids(just like Efflorescence, compared to the old version)
