I've been on since it started. It was confusing as hell and had to ask several questions. Training is automatically done every Wednesday and fights are every Saturday, you must set your fighters tactic before Saturday or he won't fight. When you search for a coach, it cost money, which they don't tell you and I lost 5K out of my original 10K that you start out with, so be careful when searching. Don't worry about fighter injuries, they will heal themselves eventually. They have a forum link under Deckagon Community on the left side of the screen but the forum is pretty dead.
My team is MMA Top Team in Rookie League #4 and currently in 6th place for my league. I messed up by having only 1 fighter, my LW, Willy Conrad and I didn't have a MW or HW which will hurt your ranking because you will need the points from each division to move up.
