You guys can just use common sense deduction here. The reason why Duke got what he got is because:
1) Duke generates money to Graal
2) Duke is leader of a huge gang..without Duke = Riots and Loss of money to Graal if players quit.
Is this the correct approach to the problem? No. Did it happen? Yes. Can we do anything about it? No.
Now, they will never admit that kill stats and all that is important (ego) everyone knows it is important, or else why would players play for stats? The more stats you have, the less noob you are..everyone knows that mentality if you are a gamer.
You don't play counter-strike and try to get the highest score or best kill/death ratio for nothing (even though it is eventually for nothing)
