You could probably make $10k faster by turreting, or basing. It's going to take about minutes on average if you do the most efficient means of respawnsuiciding, and then you are still guaranteed nothing, except looking like a fool. I figure: If it is too good, either it will be more rare, the amount will be reduced, or negative side effects will come into play. I figure, if some kid wants to do mindless suicide grinding for free money, he is really just hurting himself anyway.
