To swap for war hero gear you need to have rated warzone commendations...and for that you need to do rated warzones...and that means doing wz's at a disadvantage because I wanted to make my gear better...
And why would I grind for another bm set if I already posses one, and bioware is lazy to implement some kind of exchange vendor, so we can exchange old (re-moded) armors for new updated ones...
