Reading this i now have a question...how many seats should you have in division Iv?
I'm pretty sure there's a set attendance limit at each level, but since I don't know what that cap is, I just build more seats and raise prices when I'm selling out or getting close to it.
Agreeed. And also when you think that your team will promote, you could start building your arena in advance so that you don't waste income once you promote to higher division.
