When i read that I feel like it's against their own rules, isn't it? But at the same time, it's not adding a previlege for someone above someone else, like the desert strike ish map, it's just cosmetics, and the other one is single player. So I guess in that sense it could be acceptable.
Better late than never! Haha, j/k. Definitely would have been cool if done sooner. It does line up well with most of the game now being free at least, so its micro-transaction time. I doubt they'll be many more premium maps, but hey blizzard if you read this, I could make Stukov 3 as a premium map! (wink wink, nudge nudge)
