Persoanlly, I enjoyed solo'ing until about lvl 15 or so. If you're having
trouble finding groups out there, try getting bound in Rivervale and
hhunting in Paw. It's usually less populated than the other "main" areas
(ie: Crushbone, Blackburrow, Mino tunnels) but folks (at least on The Rathe)
seemed to be more group-oriented. Rarely did I go in there and NOT get
asked to group.
Also, this place will keep the exp coming til you hit lvl13 or 14.
