Thanks for this feature, I can finally play my priest in open world! I love healing on priest, but hate the complexity of shadow and those maaany rotational buttons, never coulhave wrapped my head around it. So I hated doing WQs and low dungeons as shadow, but now I actually enjoy it!
I am no using it on healer, that would be problematic, but for just doing stuff in shadow, its amazing 
Cheers
