I believe I fit all of the criteria:
Maturity - I have consistently demonstrated on the forums that I have a great deal of maturity.
Respect - I agree that I should be respected above all.
Teamwork - Yes, it is important that my team works to keep me alive without stealing my kills.
Good Sportsmanship - I have very good sportsmanship when I am winning.
As you classify you and your members as barbarians (and as stated, you are not role-playing), it is only natural that something should be done about this. On the grounds of the respect clause, in that I am much more respectable than a barbarian, I respectfully demand that you maturely step down from your position as clan leader and concede your position to me.
