We tend to forget here on the boards where we like to have higher level discussions about endgame events, but these sorts of issues don't affect most players. The vast majority of players spend the vast majority of their time not raiding. WHM my be behind in the cutting edge progression meta, but it's perfectly fine in the rest of the game (relatively, lilies still suck no matter what.)

That said, I'd rather see WHM brought up than SCH and AST brought down. WHM has always been the "safe but boring" healer, but as a concept that doesn't play well in the current game design. They need a support gimmick (cards, faeries) rather just a "more heals" gimmick (lilies.) Maybe in 5.0 rework lilies into a party buff mechanic or something.
