Yes, if you "leave us" for the next season there will be no one else to compete, so fingers crossed...
About the arena, I try to keep the proportions optimized but I go section by section, I find that way easier. I think you are doing a better job that me in that sense and optimizing prices which I don't.
Great game 1, btw, your defense is simply too much for my guys. Think you're more than ready for the next level. We'll welcome you in Handitan in a couple of days: match ball!
