I've noticed a couple of times in the last month when someone and I have gone to use Pro Host, it has been set to no elo.
This is something that is blocked from us changing, so we need to get an admin to turn Elo back on which is at least an annoyance for us and the admin.
Whoever turns it off can they please stop? There is a casual 1v1 room and the ability to create your own game and turn Elo off. The Pro host is the only room of its kind.
