Sad to play by yourself RobotE, don't make me cry.
I recommend friends. You're playing the same game as everyone else, already a common thread. Put down the rock, be honest and make some friends. Be happy.
I find the best part of DK is the guild and chat. There are more important things than gems.
Don't make excuses for losing. Everyone competed in the same manner. Besides, the screen shot I saw wasn't even close.
I hope you win the lottery next time.
