Really good.

But so many people lose interest when I tell them there's absolutely no way to play together. I know the anti social crowd will be all "SOLO QUEUE ONLY IF YOU ALLOW EVEN DUO QUEUES IT WILL RUIN THE GAME" (despite the fact that this doesn't happen in any other pvp game)... but this really hurts the social aspect of the game. Queues are good now, but eventually they'll slow - allowing people to play together would draw in more people and help keep it going longer term.
