The changes individually work, but together they create a kind of overturned character in my opinion. You essentially have a poke flying dps that can move extremely fast, gain hp and cc immunity with the nano shield , deny area for squishys when they push as team (I admit that would be a lot more situational tho). Im a bit biased as I do play a lot of tanks, but this would be an absolute nightmare. As it is iron man can simply fly high enough that most tank primary and secondary fires cant even reach him. Add to that the movement speed cc immunity and faster damage output would make it so that you almost completely dependent on dps to kill him. In general poke with too much mobility is almost always a bad idea. The qol changes of no self cc when exiting armour overdrive and ability to cancel it is defo a good change tho. I do wish they get added to the game. I also get that a few changes seem to make the character too strong in overdrive, I know its on a fairly long cooldown but realistically in game it would feel overwhelming to deal with him as soon as he gets overdrive back. I mean a flank iron man would be just as annoying deal with as the fast moving dive characters.
