I think it is because Kishi has already started to troll Madara, even before the Gai thing. First he leaves the Gokage alive for absolutely no reason whatsoever. Than his Gunbai mysteriously disappears from the battle field. Than he drops the sages weapons becuase for some reason they are heavy (really, de faq? How come Obito never felt that?), and than he says he doesn't care about em and leaves em there (come on, if this aint plot no jutsu than I am Michael Jackson probably). And than comes Night Gai. Honestly, I don't care how fast night Gai is there is no way he should be faster than Juubi jin. Juubi Obito was so much faster than both BM Naruto and BM Minato, who are almost instant in speed, Madara is supposedly faster than instant (Sage FTG Minato), yet somehow Gai is so much faster than this dude he can't even react or follow him? Pure nonsense.
Oh did I forget the other plot device against Madara, the 'Everyone who sees perfect susano'o once never lives to see it again so I won't use it ever again even though it would have easily made everyone's, including Night Gai's attacks meaningless. I've heard people sayin Madara has too much plot shield, really? Yaw blind? Jus look at all this plot sword stabbing him over and over again.
Anyway, bottom line, I think the plot sword is taking its tall on Madz fans that's why there so few of em now.
