Aquatic ruins (krait / jellyfish)
Snowblind (sons of svanir)
Solid ocean (jade monster)
Underground facility (dredge)
Urban battlegrounds (you're a charr)
Uncategorized (asura building)
I dont think a thread like this has been made before? Anyway, also post the difficulty scale you're in (because some nice fractals get much more annoying past a certain level).
My favorite is Uncategorized
Most hated is swampland (2nd place: dredge).
