So the only thing that matters to you is playing a game, it does not need to feel good to you as long as you are able to complain about it.
The 6v6 that was decided over a feel was, and i am assuming with my OPINION, the only right course of action with it feeling more fluid for a team system, not as slow paced as it could of been and the maps do not nearly feel as large as they could of with less players per team.
There is reason as to why the game is 6v6 you need to consider and you should stop complaining about a feature made or a feel. Because if you are having fun, then that feeling was right all along.
I am going to ignore anything else you say, you are just becoming more ignorant by the second as most High SR players are in the first place.
