Xatu, is this you? How is OU an example, when you clearly aren't taking in consideration the ones that really need HA?
Do you need us, to make a drawing for you to understand which mons might move up? Or do you lack that much basic knowledge that you don't even understand the vialibility of some mons once they get HA?
It's not about if it's usable or it isn't. If someone wants the other ability they are forced to rebreed it, something that can easily be avoided, I can afford to rebreed any comp I want, but the same can't be said about newer players, or even you in the future most likely.
Also, just curiosity of mine, do you even know what I.Q. means?
