Some of my 40k buddies got into the beta, they're really enjoying it thus far - one of them is saying that ret paladins are currently doing way more damage than any warrior, hell, even prot warriors seem to be more killy than fury/arms.
I'll be waiting for the actual release, maybe hope for a christmas discount. By the way, will you be able to buy forever game time from from those tokens you can buy/sell in retail?
