Possibly make a multi spec? Give players 2 specs.
Warriors: would be able to switch between 2h dps and 1h/shield tank
Mages: would be able to switch from aoe skills to healing skills
Archers: would be able to switch between bow skills and dagger skills

This would allow classes to have multiple roles to play. Would also give plays more to go/work for.

good idea? yes..no?
