Stricter activity checks. Characters should only qualify as active if they've rped with three different characters. Threads should only count as active if they continue for at least six tag turns and if they have a thread with in the first few days of the BR beginning.

The Villain should be more involved, it would be cool if the Boss secretly had a participant chosen in random to do their bidding/evil for them or something.

Heaven/Hell threads would be entertaining too.

And just a suggestion for the muns but: Deaths should be decided randomly with an online coin toss only to give more surprising twists. It felt like threads were really predictable.
