Found this vid on youtube of the pc costumes and new taunts- http://www.youtube.com/watch?v=yvjuaoFCyV8
I don't know if you know this but that has been one of the Sniper's lines since the game came out... Also I'd like to think the new Gunner taunt and the center of the new map was inspired by our Sumo matches.
Now the Assassin just needs to plant her sword down, jump on it's handle, and do a little jig. That would be even more awesome.
Might they have designed a map with some intent to make it fun for Sumo? I don't know. Does it have easy ring outs?
Grec, you're trying too hard, as always. I like the new Support taunt. Unfortunately, I like the old one more. :|
