I played 5v5 Nid today and it wasn't as exciting as I had hoped... 5v5 Alistar is so damn hilarious though
And that XJ9 kid has always been known to be a little on the weird side... there was a point where he pretended to be a girl or something (dunno specifics)
I think you need someone who has a slightly modified game client to make the game, dl the client yourself or alter it yourself. Might just want to join one of the rooms.
