This video and the one about sprint/clamber were superb.
Over time I've realized that most Halo players want the same things. People will defend their crutches like sprint and slow kill times because it gives them a sense of control. They don't think they should have to die every time they're in a bad position, so being able to run away makes it seem like they have more choices. What they really would appreciate is having the chance to win a losing battle. Of course, that depends completely on the difficulty and power of the weapons, but most players haven't experienced games with that kind of balance.
