Pretty simple It was like this on Voobly. It was like this on HD. You make your own game room to your setting’s liking, there’s a small criteria of needing to be balanced to be considered ranked (like on HD, the teams could not be lopsided, no 2v3s), and you can play whatever map you want.
I’m not exactly a good Arena player, but I have friends who are and heavily invested in the scene. I’d personally like to see more pro ranked Arena but it’s like a a slim chance of lucking out and getting it in the queue.
What to do with the queue though?
Simple: Keep it!
Just add a ranked lobby as a separate tab. The queue is just fine, but an independent ranked lobby addresses literally every criticism about the queue. Maybe have a separate elo tag for ranked lobby and ranked via queue to give an idea if theyre an arabia/arena only player or any time any where player that the queue helps develop.
