Just buy the entry level blue gear, oh wait BW took that out because, because.... I have no freakin clue why they took it out, more BW pvp noobness.
I bought that for my sentinel the first time I hit 50, now with my gunslinger just hitting 50 I'm a bit pissed. 10% expertise and level 50 armor values really makes a huge difference.
Entry level pvp gear BW, cmon this is more basic stuff that is crushing pvp in this game!
