I've found many of the quests to be really fun, especially when grouping w/ others. I went into a gnome cave up by the refugee camp across the lake from the plains, and it was really cool, although the 3 of us got our butts handed to us on a silver platter. Lots of 14 lvl 3 dots that were a little too much for the 3 of us.
It sucks to get your butts beat by a bunch of midgets.
Of course there's the common "Skin 15 lizards" or "Slay 10 dragon turtles" and stuff like that that gets boring real fast. But the others where you can really explore vast underground caves and such make it all worth it to me.
