Based on my observations, once Savage releases, WHM is going to be bottom of the barrel assuming damage taken increases. While all the other healers have plentiful oGCDs to cover damage windows, WHM is left wanting. Yes, Afflatus Rapture / Afflatus Solace can still be seen as 225 potency, but with the increase of damage on basic damage skills and the ability to weave with them, they lost their flexibility that other healers lacked to spend their plethora of powerful oGCDs (SCH having to Ruin II and for the sake of argument SGE having 2.5 sec cast on Dosis as well). Additionally, Dia was gutted for some reason? Perhaps AST is weak enough that WHM will still be the best 'pure healer' or whatever bollocks they named it, but then people might just run SGE and SCH and say f. it to any 'pure healing' and just throw their two dozen oGCDs at mechanics while losing 0 dps.

With the overkill of Piety on current top ilvl gear, I don't really notice the loss of the 'good' Thin Air just yet.
