I play WoW still, and do it with game time cards . Largely because of an issue where I gave SOE my credit card number and after cancelling EQ they continued to charge me for like a year. Of course this is largely my fault for not paying more attention to the statements (and I'm not denying that). Still I am vastly preferring game time cards both to prevent my mistakes and theirs.
As far as the Craigslist post goes, I half expect to see an article up about this on Encyclopedia Dramatica or another satire site within a couple of weeks. It sounds like the kind of stuff they would do, especially to pad out the "Gaming Portal" section. I look back to the Craigslist "scams" they immoralized with people putting up ads claiming to be kinky submissive women and then posting the responses and pics they received on ED.
The posts this guy will probably recieve full of people trying to sell themselves for such a job are probably going to include a number of very lulzy ones.
I think it's false because if the guy is any good (which I am assuming) he can probably meet other good people who want the same thing even if he's an arrogant twit. Also alienating your server is meaningless now that you can pretty much pay Blizzard to change your character around totally and move you to other servers. I mean you can go from alliance to horde, change gender, and everything else. The guy could totally re-invent himself for a fraction
of what he's offering if that was the issue.
I could be wrong but I'm guessing it's "for the lulz".
I personally avoid the arena, I do a bit of battleground PVP once in a while (I used to be a lot more into it), mostly nowadays I'm a carebear semi-casual PVE endgame raider. Laugh if you want but I have fun and that's what the game is for.
