I dislike the idea of working alone, so maybe forming his own group which can grow since he can still only take on 1 dungeon at a time. Doing things solo on your own is retarded since the key to our current world right now is civilization aka working together. sure he himself can solo stuff, but he is still only 1 person and with multiple strong groups tackling on dungeons at a rapid rate, he can dominate absolutely everything and eventually hold a monopoly on EVERYTHING as other groups would either have to assimilate or go bankrupt.
