No glaring weaknesses? Have you seen his midscreen damage? You're lucky if you break 23%, and every combo ends his momentum. He has to take extreme risks to break armor, and his 1-bar midscreen combo essentially doesn't work on female characters. His +7 projectile pushes the opponent back too far to really capitalize on the advantage. To get his high damage in the corner he has to rely on a -16 special.
Don't get me wrong, I think he's a really strong character, but his bs doesn't come close to the other bs you see with Quan, KJ, Ermac, Scorpion, Sonya (50% xray!!!), SZ, etc.
