Well, Baton beat us mostly in 1v1. Ace and i won against him twice in 2v2 yesterday.
I cant speak for the others, but in my view 1v1 is a tiny little bit different than 2v2. With no 1v1 training you can get in trouble very quickly.
I for one didnt play a serious 1v1 for many month if not years. I dunno when the last 1v1 tourney was (Ace Season 3 or something) but since then it was mostly 2v2 for me.
On top of that, Baton played us in "his" setups (EU vs Russia). He had a very good battle plan and forced us to fight on his terms.
I think i played in 3 times in a different setup (two times being Asia vs Russia) and lost only against the Star.
That being said however, Baton has come a long way. He plays disciplined and very aggressive, he knows what will happen in a game and its very hard to surprise him. Its unlikely that he ll get a win percentage good enough for boss status, but IMO, based on the displayed development he has earned it anyway.
