And why exactly is that considered a shortcut by you? What are you bypassing that you don't need to do later by taking that path? Yes, you bypass Kraidzief and get right into the megaman section....but you have to backtrack and fight Kraidzief anyway, so that's not a shortcut.
A shortcut is a way of bypassing something to make things quicker, not bypassing something so that you can do it later and take the same amount of time.
The only true shortcut in the game, really, is the room of transportation, and utilizing the kraidzief warp so that you can head immediately to the megaman area.
I also wouldn't call people "dumb" when you can't spell it.
