I'm too cynical for that. I mained WHM from ARR through Stormblood. I've seen competition from two busted overpowered healer jobs claiming that being extremely good at everything is just "good design". I healed through 20% Balance and Scholar doing as much damage as Ninja, while being told those things were "just good design", "WHM just needs to be brought up a little to compete". I've also been around when WHM dares to have a patch where they do more damage than the other healers and the screaming that entails. The thing is, WHM is never, ever going to be a well-designed job so long a Square keeps hammering this awful "pure simple straightforward no frills" fake identity onto it, and the good-at-everything overpowered healers are going to say "there there, I hope they fix you someday" until the heat death of the universe. Square has already demonstrated they'd rather topple the entire design they set forth for both AST and SCH than EVER give WHM anything interesting or fun to do.

I had a point in there somewhere, but it got lost in my being angry about how terribly Square has treated WHM since 3.2. I get what you're saying, but I still think that being good at everything isn't "good design". It's overpowered design that creates role imbalance because it warps the whole role around itself. Everyone else has to be just as overpowered, or be left in the dust.
