In case you haven't already, when he asks you to try out PVP, do it even if you aren't interested in it yet. You get a free gear set that can be used by your PVE characters as well, so some of it might be upgrades depending upon what you have.
My biggest problem with PVP was that I haven't seen half of the cards before, so I sat there looking at all of them so I ran out of time. I know that I could have studied them during the equip phase, but I figured I had no idea what sort of synergies I'd want and I'd just see how stuff came up. Unfortunately, that meant I had to read every fucking card almost.
I'm loving the game, but I'm not sure I have the mentality to get into ranked PVP stuff. I've got a long ways to go before level cap, and hopefully by then it gets raised, so we'll see. I bought the premium membership thing to get more loot and to support them, but I can see a point where PVP will be the only thing to do after awhile. I hope that day is a long time coming though.
