imo the defiler is the mt shaman for several reason.
1. ancestors is needed there more than anywhere else.
2. soul ward- yes thats a raid wide ability but helps when u have other healers in ur grp to help u regain your health without having to stop ward casting.
3. hp buffs are slightly higher and high end raiding every little bit helps.
4. power regen- canabalize is a serious ability...helps more than some realize seeing how u dont need as much attention on the low power scale.
now i'm sure there's arguments about my basis but like i said it my opinion
