We'll probably show seperate elo depending on which mode you're playing [elo - gladiator elo]. So if you're in a gladiator room it shows your gladiator elo, whereas in regular rooms it shows your [regular] elo. We'll also have to seperate rankings on the website for that.
I see some other / different suggestions in this thread. If you want us and others to pay attention to your individual suggestions please post your own / seperate threads for them.
