OP, I've given up caring about the DT system since the rotation system started. It used to mean something huge if you were even a DT2 member. Now it's nothing special, really.
Theymos has never made the lottery provably fair, so it is possible he can manipulate it - it's still centralized, just more randomized. In this scenario he would be trying different setups and analyzing effects, to eventually replace the randomness with more stability. Otherwise, what's the point?
Opposite to your quoted post, I've actually started caring
more about my trust list recently. I realized I was ignoring the good to focus on the bad; the best way to kill the plague is to support the cats and let them kill the rats.
