I think the logic is more like: everything which was in beta is free, every addtion will premium.
please post bug in the bugs report forum so that they can see and fix it.
btw solid update.
I really recommend the rotational 1v1 or 2v2 play type like the Rocket arena 3 style.
For example, I suppose there are three players, A, B and C.
If A beats B, A will fight with C. And then if C is a winner, C and B play the next round.
Though I'm poor at communicating in English, could you understand? I'll believe so :)
