I'm still waiting for the day WC Maxi comes back to the US and dominates at Evo. Before my time sadly.
Yes, Americans, especially as of late, are becoming data obsessed. There is a huge emphasis on frame data and risk/reward. MK9 is the only recent game that has diverged from this where you see people trying to play simply by reading opponents. It began in the latter days of SC2 and most of SC3, where frame data was brought up every other discussion, mainly due to the high safety play. Ironically, if you look a the "old school" players from SC2, they didn't obsess anywhere near over frame data as players do now, even though SC2 probably was the most turtle friendly SC of all. I just don't get it. After -20, does it really matter if a move is -21?
