Dungeons are becoming style over substance.

[Shurrikhan]

No need to be insulting. In fact, I doubt super casual players have SE's ear more than any other group.

That doesn't much matter so long as they have the dev's focus, by errant perception ("more than 2 dps spells on a healer is 'too hard'") or not.

If all other groups' otherwise beneficial opportunities are prevented to maintain some seemingly mutually-exclusive service the devs believe they are providing to some particular group -- especially when those prevented opportunities are especially design-efficient (as simply having more than a single difficulty setting would be) -- that's problem enough.
