You see, I also have issues with this Majority in a Lottery Vote because "lottery" means there are odds. Locking out the odds because 3 people pick the same champ no longer makes it a lottery, and plus it defies math. Here's how math, and a lottery, works:
100%/5 = 20%
Each player, therefore, should have a vote weight of 20%.
If 3 players pick Yasuo, their combined vote weight is 60%.
That means there is still 40% vote weight unaccounted for.
If the other 2 players pick Caitlyn and Jinx, there vote weight should be 20% each.
So the lottery odds should look like this:
60% Yasuo
20% Jinx
20%Caitlyn
What this SHOULD mean is that Yasuo is 10% more likely to be picked over Caitlyn or Jinx combined. What this SHOULD NOT mean is that Caitlyn and Jinx are never picked, because the math still allows for them to get picked, albeit at lower odds.
The current system is utterly stupid, and whoever designed the math calculations needs to go back to school and re-evaluate his or her life as a programmer.
