What i am able to understand from your comment is that basically there is no skill expression, and all you can do is rat and try to play the numbers game rather than playing Apex, the movement/shooter battle royale game.
Sure people want to win. But people also want to have their skill acknowledged. Which is why they play ranked: To compare their skill relative to others in their region.
Ones ability to decifer a poorly thought out point awarding system, does not directly reflect their mechanical skill and game sense.
Lastly, your comment does not provide any explanation as to why it should be a Hidden system masked by an arbitrary rank, rather than scrapping the useless ranking system and just using the MMR, or visa versa.
Personally i like the idea of the MMR pools as it has the potential to be a more accurate depiction of skill... If only it were implemented with full transparency, reasoning and not masked beneath some superficial rankin...
