The return of Dungeon Fighter Online (OPEN BETA PT. I STARTS MARCH 24TH!).

You're right, a prolonged alpha is useless BUT they didn't know it would grow this fast and aren't prepared at all for a beta. They have to bring up new servers, patch the game PROPERLY against botters and hackers, change the way people are connecting together in the game (there were a lot of issues in nexon era because of the peer 2 perr connection type, etc.
I would expect the alpha to close early june, and the beta to come out late june.
