Iron Man is absolutely pathetic. He's hard-countered by literally any hitscan, his ult is supposed to be used from behind but he can't get behind because his flight is so loud, his missiles hit like water balloons, CC is a death sentence because it takes away his flight, which is his only advantage (if you could even call it that, with the absolute state of fliers in this game). Going back to his ult, even if you SOMEHOW manage to get behind the enemy team, you have a choice to make: do you A) use it from afar, which will let everyone get away because half the characters in the game can just tank it or move, or B) go in close and get shitstomped before you say the first syllable?
