Since the Tourge slots in the Mr. Tourge DLC cost rare Tourge Tokens, I'm wondering if my expected value for them is above zero; e.g. if I play a million times, statistically am I likely to have more or less Tourge Tokens than when I started with? I know I'll get guns and stuff, but the net TT are all I care about; they're annoying to come by and can be used to buy legendary weapons. It costs 5 tokens to play and, from my limited experience, doesn't seem to give a very high payout.
