I personally love having a SCH with me in 8 mans or in 4 mans healing if im tanking or dps.... Yes WHM is more a pure heal healer, but it gets crazy when in some fights you have to move and adjust to not get killed... SCH is way better for that, your pet is OP, the shields, buffs and absorbs that a SCH puts out is amazing... I have seen SCH solo heal Titan(WHM kept dying) and Garuda... Anyone who says SCH is not a great healer is either dumb or maybe has just had bad luck with bad SCH's...
