I dont think Krillin will kick Stark out his armor since he had a problem knocking down a steel door.
I can't believe you took him seriously. Just ignore him like everyone else does. By replying to his ridiculous post you could ignite a flame between the two of you given the fact that he did not even put any amount of logic and reasoning into his post and simply said that the attack of said fighter will harm said fighters I.E "Spider-Man's web will hurt Hulk", complete bull. Its quite clear we know who the winner is so lets leave as it is.
