Suggestions for improving Maple Story

I don't like the idea of buff mules. I know some people rely heavily on HS/HB/SE mules, but it gives people with multiple computers a huge advantage while playing the game. It doesn't take a lot of time to make a buff mule these days, and it's annoying to hear how HS isn't an advantage for Bishops because AMs can bring along their HS mules.

Actually, I'm just unhappy with how much of an advantage people with multiple computers have in general, be it in CPQ or xferring items or anywhere else. Not sure how this problem can be addressed, though.
