The message is annoying...but its just a message...and I forget its even there as soon as I see it...there are for more important things to worry about. Like upgrading the glamour dresser to be something more useful. (More plates/tie in to jobs, etc)
Speak for yourself. I don't give a hoot about the glamour dresser. This on the other hand is something that actually affects stuff I actually do (and particularly makes beast tribe dailies more annoying to do when I'm already 450/450. Like someone else pointed out... what does the game expect me to do, not hand in my *daily* quests until next week?)

Removing this message/popup should also be such a trivial task that it really wouldn't be cutting into development time for other things, so the whole "either or" standpoint you're trying to adopt is inherently silly.
