Gotta say, I am mostly PVPing right now after I hit 50 some days ago and the way they decided on how to get PVP gear is absolutely despicable.
You have to grind 800 warzone commendations for one of these purple epic bags - then you MIGHT have a PVP set item in it if you're very lucky - or you get 3 other commendations.
The knack is, the people who are lucky get itemlevel 136 I believe it is epics - the ones who aren't lucky - me namely, have to farm 39 of the commendations to get a set item that is of inferior quality than the ones who got the luck of the Irish.
Seeing people running around in the full armour while I got 2 implants so far and haven't even got enough commendations for the first freaking item - highly annoying.
Other than that, I hope the raids will be fun.
PS.: I shouldn't have rerolled at 46
but Sith Warrior is just way more fun than Imperial Agent was - at least in PVP.
