SC2 arcade is dead because pepole just either simply don't know of it's existence, either played maps and don't like them simply, becauce they uploaded in SC2, but they aren't SC2. So bye bye your game is almost dead.

Only popular map in playground is Shit Strike HotS (If we don't talk about Korean server). Shit Strike HotS is a popular map, because it's a nexus wars rip-off, that was a pretty popular map, becuase this map wasn't uploaded on playground, but it should be. It's a good choice for fuckers, that play SC2 for 5 years and still don't know about existense of playground. Also Shit Strike is a fucking imbalanced game, Protoss is hillariously OP and Terran is hard to win.

Say bye bye to SC2 mafia and it's community. It's almost deeeeeeeeaaaaaaaad.
Ban me haha i don't care, i don't play SC2 Mafia anymore tbh.
