I'm looking to get some feedback on 10m raiding when various encounters require 2 or 3 healers. I was previously a Shadow Priest for my raiding guild, but after reorganizing, I've switched to healing too. However, due to some encounters requiring 2 or 3 healers, I've been asked to switch to Shadow for fights that require only 2 healers. This is for normal and heroic modes.
I'm sure I'm not alone in this predicament. I think most heroic fights require 3 healers, so I'm leaning towards optimizing my gear for healing, but then that makes for bad DPS (especially with all the spirit). I typically heal as Discipline, but haste is regarded as one of our lowest priorities, while it's very high for Shadow. I was considering that Holy may be better since it values haste a lot too. Or should I consider a balanced approach? Any thoughts or feedback on this would be appreciated. Thanks.
