How do ppl do it?

How do I eliminate my frusteration from grinding the same content? easy, I don't. I also don't use the Duty Finder. Don't forget, you get stones of philosophy as early as the Dzemel Darkhold. If you want variety, run them in order (Dzemel Darkhold, the Aurum Vale, The Wanderer's Palace, Castrum, Praetorium, Amdapor Keep) there's more than just one dungeon. Sure you get more stones from Castrum and Praetorium, but there's no reason to stress, it's not like the game is getting shut off next month. I don't have all of my DL gear yet, and I probably wont for a while still, just run what you can, don't let yourself get burned out.
Oh, also Primals give (while a small amount) both Philosophy and Mythology stones, they also have fairly high level weapons to have, so don't forget that's an option too.

Here's a little advice: I do Brayflox Longstop at level 50- you know why? Because I LIKE DOING IT!

If it bores your mind out doing CM, stop DOING IT! You trying to farm tomes for gear you say? Oh please, take a break, what's the hurry? The game only just started and you want to finish it in a month, that's just wrong.

Try to enjoy the little things, that's what makes life interesting.

Do you still remember people say "it's ok, lets enjoy the fight, no big deal" from below cap level dungeons, while leveling your first character? It's that kind of attitude that will make the game better!
