As part of a stream that I moderate, we're putting on a small League tournament through Achievement Hunter's tournament system. We have slots for three more teams of five at the moment, but, if there's enough interest, we'll find a way to make it bigger.
I'll be going around to the League groups on Achievement Hunter/Rooster Teeth spreading the word. Even if you're not interested, we're going to try and stream the matches so you can all watch. It's not for about a month, so you'll have time to find a team and play.
