True, but look at a spell like paralyze. The Dev's had treated that like a over powering spell that can make a fight lopsided in the player's favor......... It's paralyze, can you ever remember a time some one said thank god we had paralyze on that thing. It made it so much easier to beat?

Being the case, I'm sure they'd frown upon a super beef up phalanx in the same way. The thing is if they design mob's around an ideal damage which would make call for a buff like this to help a group to survive content. It would add greatly to the strategy of the combat. I would see it no different than content like VW where you constantly spam temp items to survive the fight. Except it would be more of a 1 shot deal.
