I think we should consider all the job's toolset, broil is very strong, ub in my opinion I would never trade my WHM Regene for the SCH's retarded fairy.
Actually I can't really figure if there's a top tier healer because I'm probably using badly the SCH, instead I feel stronger with WHM.

But I can agree that Broil could need an adjustment, imho I would see the DR applied to it, as the other healers' toolkits.
I won't like to see it swapped to a Infirmery or even worse Blind debuff.
