Well even after level 30 you still get class abilities and traits until 50. That is another thing i forgot to cover, jobs have no traits whatsoever. any passives for jobs seem to be tied to abilities or to the class itself.

I hope its more than just PvP as the gear will have morale there and there would be no point in going in with allagan also we would probably have new PvP abilities and wont need crossclass abilities much.
