Alyx might not even need that much rallying. Gordon got 65.5% on Yoshi with none. Yoshi himself only got 63% on Liu Kang, and this was two years before the MK resurgence. Maybe the Nintendo guys outside of Mario are just weaker there. I can't remember, but did Kerrigan get significant rallying against Bowser?
