I think the hot bout feature helps even things up a bit. Correctly picking an overwhelming favorite, and correctly picking the winner of an even match, shouldn't be worth the same points. Remember, you always have your record to show how well you are doing overall. But, fantasy points wise, you've got to recognize when someone's correctly picking "harder" bouts.
However, instead of giving double points for the entire score of a hot bout, I'd be fine if they just doubled the 5 points you got for the winner. So, instead of a max of 22, you'd max at 16. After all, the point is that these two guys are too close to call a winner...not too close to pick the correct finish. So, give 10 for the win, then 2,2,2. Seems fair, no?
I'd be cool with that change, but no other.
