Idk man, a guy relegated to my league in Div 4 and he has a 20k arena, that's not really fair he has a huge advantage already. Moving a rich micro team to some Div 5s or 4s isn't really that much different than that guy having a 20k arena over all of us 6-10k arena guys. Maybe if they move the micro team to a new nation they just reset their money to 300k or something like that. I don't see why he can't keep his arena, there was a guy in my D5 that had a 24k arena, luckily he wasn't there but he would have crushed my team if he wanted to.
