I appreciate the healthy dialogue to at least have some conversation in the open around promoting more collaboration. It's all healthy to me.
For the collab multiplier, an alternative is to dampen the multiplier down to a 1.5x or 1.2x, per vote. Therefore, lessens the perception there will be a disadvantage submitting a sole submission vs. a collaborative submission when it comes to getting votes. That's if you get any votes at all.
There's also opportunity here for a sole submission to be absolute fire and is clearly a better beat than any other collaborative submission, therefore the votes will speak for themselves, regardless of a multiplier.
Ultimately, these are beat battles, weekly practice, a place to escape - so the thought was to present a new challenge to test. 5XVT was spot on. We won't know if it works or not unless it's been tried out.
