Now before I jump into this. This is Anecdotal. Because the game happens outside of a Dummy Parse. Sometimes how things feel is more important than what shows up on a spreadsheet.

I think that Warden falls victim to being half-baked. And it's not the only one I think there are aspects of other classes as well that lack vision and the ebb and flow of balance changes reinforce that idea.
I think there are players that don't care about class fantasy as long as their class performs well. That's where the Player Power comes in, nothing matters except for the Output, "as long as I can hit such and such dps or do X content, my class can be a potato for all I care."
I would argue that Class Fantasy is more important than ever and having both Passive and Active skills that mesh well together is very important and a class with great Class Fantasy will in most cases out perform one without.
I think among all the classes Dragonknight has the best Class Fantasy and in both PvE and PvP, they performed super well because everything meshes well together.
I really think Zos should take their heads out of the Spreadsheets and look at the Fantasy of each class and the feedback from the community as well.
That's my 2 cents.
