is true, for old player of mmorpg, that have try a lot of different challenge in different mmorpg, actually the game don't offer a very high challenge, but for people that have never been into endgame this are really challenge, i have a friend that was never a fan of endgame. she is now totally hooked, she enjoy every boss she beat, more important now she even try to face this same challenge with different class (she is WHM) now she try it in GLD and it's like a new game for her.

all of this for say, maybe you need to change your way to see the game and simply enjoy it as it is.
