LOL, Columi grind, you can get that way faster then you can get PvP gear.
I would tend to argue that the gear should be equally viable on both sides of the game.
PvP is based on a comms system where you can still lose all your matches and earn comms for gear. Since the latest patches it's all too easy to max out on medals plus the daily quests so you're pretty much guaranteed any
piece of WH after a couple of hours of play which stomps all over columi and is on par with rakata.
Just getting columi is a chore compared to it despite flashpoints being repeatable you still have to roll on the gear which isn't guaranteed to drop for your class. Not only that the mainhand which is considerably weaker than the WH piece (that you can pick up after at least 15 warzone matches guaranteed) you either have a chance drop where you are competing with 8 other players in a roll on KP once a week or you have to get to the end of LI HM which not everyone can do and hope it drops for your class and win the roll on it.
Anyone who says WH is a lot harder to get than columi after patch 1.6 is an imbecile, they're basically giving PvPers the guaranteed gear on a plate which basically is capable of playing some of the tougher PvE content in the game up to EC HM.
Where's the logic in that? It's almost like BW want people to skip gearing up PvE gear the normal route and just grab a set of WH and jump in an HM operation.
