Just hit 26 on my 3x mages earlier today. A couple more levels aoe-farming stockades then I'll move on to something else.

Does anyone know the minimum level to zone into Ramparts? Once I get to Outlands 3x mages will be joining up with my warrior and shaman for my 5 man team.

Edit - Found the answer, apparently need to be 55 to zone into Ramparts.
