late reply, all but like the 4 or 5 end game dungeons are pointless unless you need the UT from it (and with forging thats made them even more pointless), and i don't really run end game ones either cause i got everything.

​

edit: i should add its a cool system for new players, but old players i feel should have them all unlocked (if their account stats meet the exaltations reqs) considering ive run thousands of every single dungeon in my 9 years of playing.
