Yes, there are instances, although most of them are at high level. The lower level instances are run, but not as much. At your level you should've seen couple - Fungus garden and Barren Caves (and the one in Moongrove)
By "dungeon finder" what do you mean? A way to find instances? If so, then no. Or maybe a way to find a party for instances, in which case there is one, but nobody uses it much.
Might want to post in "new player" forum instead of this one. This forum is not used much.
-- Rustyx --- 92R / 92S / 92M on Reni (Guild KnightShift). Yes, running the new FOTM R/M, cause I am not elf enough to be WD/S.
Oh, and people who have more than 3 classes are clinically insane.
