Might I put out that this thread was put on the basis of a individuals skill level at TW.Well then you are a rubbish TRIBALWARS player. You'd be great at INDIVIDUALWARS though.
Seriously though if you are only loyal to your friends, then how do you expect to ever make any new friends? That's just antisocial.
Even if you didn't want to make any new friends, why not just make a tribe with your close friends? If those were the only ones you were willing to support and attack for then why even bother having the rest of Bi! in your tribe when it existed.
On skill level, Grant was one of the best players on UK4 to date, however, overall he was rubbish, due to the Bi! story.
