Remove majority
It's stupid, poorly conceived, and extremely unfair. If you have a three man premade you can dominate One For All. You want to play urgot? Well you get to. How about Aatrox? Yup. Udyr? Definitely. Eve? No problem. And those two poor fools have to do whatever y'all say without so much as an iota of input.
Even in the case of a 4 v 1 there should still be a 20% chance that the one guy gets to play what he voted for.
I'm personally guilty of this, and quite honestly I'd be more than happy to give it up. It's toxic and very excluding of duos and solos.
Please, PLEASE remove majority pick in One For All.
etc) That concept goes both ways, and quite honestly whatever happens, happens. Provided everyone has consistent and guaranteed input.
