Anyway, here's an idea I had: we could have a "Countdown till the New Year" event where the objection is to complete the most battles before the New Year rolls around. This would start at around 8 PM EST I'm guessing. This event would likely have only one tier allowed so that everyone can battle without having to ask which tier to use beforehand. I'm not sure if playing in two or more battles at once should be allowed however.
I like this. Generally those playing in two or more battles struggle to win so maybe make it to win rather than just to complete, so that they can have that option too if they're willing?
