I liked it in 11 where People could switch jobs but it took 6 months to cap a job, so we still had a situation where 80% of people had 2 jobs cap'ed at most (when i played anyway) so essentially people still had thier identity as the OP described.

Yes, i love the fact that i can be any class i want on one character, but at the same time i prefered it in 11 where everyone wasnt every class.

whats done is done anyway and i dont think its something that can be changed for 2.0 so theres not really any point discussing it.
