I’m pretty sure you do have to have some amount of skill and teamwork. Prizes are only awarded for the top 64 teams. Currently, there’s 400+ teams registered on the ladder. And some of the top teams have already played 20+ matches. And I’m assuming the way it’ll work is the top 64 teams at the end of some preset time will play in a tournament, where they’ll have a week to find a time to play their scheduled match. Maybe I’m wrong, didn’t bother to read the full set of rules. Remember, it’s Gamebattles. You’re competing against people who devote themselves to the game.
If you’re going to play on the ladder, I suggest you learn and understand how Gamebattles matches are set-up, conducted, and how to handle disputes and file support tickets. And make sure someone on your team either has a capture card or a digital camera.
