Thank you for the quick reply!
I've yet to decide what spec to play. While i do love tanking (And this is where i have my Rakata gear), in PVP it is a strange feeling. Because, as you mentioned, in 1 vs 1 i feel pretty useless. But that is negleckted if you do party up with some fellow PVPers. But i really want to be independent, meaning i can still hop into a random WZ alone and not get thrown around completely. To sum it up, i haven't decided yet. Perhaps you know of some good PVP videos that show these two playstyles? I'm not that big of a fan for the insane-smash-damage-spec-thingy though.
I know a bit about Resolve, but probably not as much as i ought to. There's a post stickied here on the forums, i'll read through that!
