It's even more worth it between 15-55, you can gain like 2 levels per dungeon runs the first time you do them with their quests. But that's with a bunch of heirlooms, I wouldn't know without them.
I don't even know what an heirloom is or how to get it!
If your goal is to experience the quests from 1-60 then I would avoid dungeon finder entirely. One dungeon clear is going to turn every quest in your log grey.
Dungeon finder dries up during the 80-85 grind as people suck at those dungeons.
80-85 was fine, but I was also priest, so success was entirely dependent on me being a good healer I had no issues, but people really did suck and make my life harder. Mages and warlocks only doing AOE, tanks not holding aggro correctly, etc. Good gravy. Then of course they blame the healer when the dps dies because I wasn't healing them... even though I was trying to keep the tank alive who was taking abnormally too much damage every hit. Sigh.
It'll be hard to resist some dungeons, though. I have fond memories of uldaman and blackfathom, and of course stockades and deadmines. ;_;
Scarlet monastery I ran a bit tooooooooo much so i might pass on those.
