Have you ever organized a boost session with 12 people? How about 24 people? I have, and the more people you get the more out of control it's gets. MAG would require a hell of a lot more people then that, and how would you go about boosting it exactly? A large amount of people won't listen to instruction even if it's benefits them in the end, people are impatient and selfish when it comes to boosting and will step over you to get there's done. MAG was an interesting concept but poorly executed due to the minimum amount of people you need to start a match.
