I have not taken part in this FATE, as I normally don't FATE grind at all. If I see one on the way to a quest/hunting log mob I will do it, but that's pretty much it.

As a result my friends who have all done this FATE have multiple classes at 50. Doesn't bother me at all.

That's the thing about MMO's, you can pretty much do what you want in an open world enviroment. Don't like it? Don't do it. There's no reason to tell the rest of the players that they are wrong for doing it.
