Considering Carbine Studios was founded by 17 members of the World of Warcraft development team, I can forgive the re-use of the terms "Arenas" and "Battlegrounds". It's the combat that matters, and WildStar's isn't very much like WoW at all.
With the June launch just a couple of months away, we're finally getting our first good look at WildStar's PVP system, and it's not looking too shabby. There's real targeting going on there, and I'm a big fan of a level playing field. Will I abuse the hell out of the in-world rival system? No, because I am a big wuss.
The MMORPG gives great video, though of course the proof is in the pudding. I'm still not sure it's a game folks will be willing to pay a regular monthly subscription to play. I suppose we'll find out in the months following June.
