Meh. I had issues the first time in Pokémon Silver version, but after knowing what I was walking into, I planted several kicks to the face of her Miltank. These days though, I rarely find difficulty in the Pokémon games. I have some trouble in some other games but only if I play on the highest difficulty. I wish they upped the difficulty a tab bit more. Since the introduction of abilities, her Miltank is more dangerous, but only if you don't have any female Pokémon at your disposal. Access to some pretty good Pokémon early on like Spinorak prevent being locked into a long drawn out battle if you have Poison use and Fire use along for the ride. Electric types also work well against her. Locking itself into Roll Out actually gives me the chance to set up a two hit.
