It is a fictional game. You can't apply your logic to it because the game has his own logic
Keep begging for Iceman to be frostbite immune....can almost guarantee that if Kabam ever listened and gave him that immunity...the first thing they would do is nerf some other aspect of his abilities in the name of balance...he is powerful already...don't give them the opportunity to ruin him.
Iceman’s cold control can be related to the slowing of molecules/energy removal from molecules. If another hero (the other Iceman) is doing this to him he would still be affected.
Its not about logic anyway he would be even stronger with that immunity its called balance. Same reason they chose not to make rider have more immunities they even confirmed this as well in a really old post.
