"not enough time to play it" OBVIOUSLY, and that´s why I said they are training hard on it. Not thinking exactly on Blast, but until next Major, maybe.
Or even, at least to ban Inferno or Cache instead of Nuke, depending of the rival.
About fer, felps and fallen, I´m not sure like you. I prefer to wait. They are experient players and have an experient coach who knows a lot the map. So, if they are training on it and let the map against 3 of 5 teams on BLAST, they really has faith on this map.
