My point is that is not the case
It isn’t random it is just what someone wants
It would be that way every time
May as well not vote
But they are since they want to
In that specific game that one other person votes for basic, the next game someone might vote for op. If you notice that basic is voted too often and you want a change, you'll have to vote for something else specifically.
Imagine playing 2 games in a row:
Game 1: One player votes basic.
Game 2: No ranks except you.
You don't really prefer a specific mode, you just want some variety.
* If you vote random both times, it might be op in game 1 and basic in game 2.
* If your random vote isn't counted in game 1 it will be definitely be basic. Then in game 2 you don't want basic again so you vote for op. You get effectively the same result, but that other player gets what he wants. Good.
