don't know if this has been mentioned but,
Quest: Old Odo's Leaf Farm
lvl: 11
icon: full fellowship
actuall lvl: 10
actual icon: small group, though you can solo it if you are quick
reason: by simply clearing all the mobs in advance you can solo this, though if you are a bit slow on this you'll get a bit of respawn, though with the right class this doesn't make any difference, so yeah, small fellowship not full.
