Yeah ok, i agree with the general consensus, its just adding on weaknesses, do ppl not realize that the reason pokemon have dual types is to get RID of weaknesses gyrados is flying because of flyings weakness to ice and waters weakness to grass
half of the metagame would stay in heart gold, where things made sense the other half would rage quit the pokemon franchise
plus dragon/fire/flying charizard would be weak to ice, no one wants to see a fire type be weak to ice
