Say you're fighting a gym leader or Elite 4 member, and you almost beat him or her. Then, out of nowhere, he or she pulls out a Hyper Potion and fully heals the pokemon. And sometimes they do this multiple times.
But if they're so great and experts in they're type, then they shouldn't need healing items to win. And for some (like Norman), it's not as easy to train for after you find that you need to level up some.
But then again, healing items do make the gyms harder. And since you can use them, shouldn't your opponent get the same privledge?
What do you think?
