What if there was a person and got all there clan members in and they let him kill them (They would all have to have diamond donor though)
1). They would not have to all be diamond donor in order to get into the server (iron or gold also works).
2). Members of a clan are nice and all but statistically, 23 other human beings aren't very likely to just roll over and let one clanmate kill them (without a valid and sound reason at least).
3). It is highly unlikely that any one MCSG clan is going to have 24+ members all be online and in the same MCSG server simultaneously. Most clan battles are a hell of a lot smaller than that anyway. I should know. I was clan battle director for #Immortals and it was a pain in the bum to get even three of our own people online besides myself, let alone the two leaders (no offense to them, they were rather busy for months on end).
