Its like comparing Grrr... to other progamers. He was in the early days when Brain was over mechanics and I doubt he would be able to adjust to the 12h regime (and he wasn't).
There can be no doubt that Mondragon, Testie and even Draco were much more talened than Idra, but they don't have it in them to get repetitive and practice as they are ordered.
P.S. Anyone know whats Slayer doing now? He just said fu BW after winning KBK and dissapeared :D
