My two cents:
One of your reward clauses says (just like my original one) that the 'Monsters' get their own bounty as a reward should they evade domination; I'd say it's only fair to them to keep a deadline. After all, especially after their names are outed, they are going to be constantly pursued; paying them off for the trouble is probably a good thing. Now, I voted for ending it on the 21st, as opposed to some other deadline, but something like the 30th wouldn't be terrible.
Additionally, another two cents (I have a pocket full of change):
I get that nobody has been dominated yet, and that's sort of an anticlimactic way to end it off. My suggestion, if you wanted to spike the frenzy a little bit, would be to reveal the names of the monsters a day or two before you DO choose to end it. people still have to guess as to their maps and classes, but you might think about giving the proverbial dogs some proverbial bones.
