Reference to the standard, please?
That’s only a theory, which has got nothing to do with how HS works.
A more fitting example: you know, if a boxing world champion goes on a ring and gets sandbagged by a sack of manure ten times in a row (not once in a lifetime), does that mean his ‘MMR’ 
got too high and he met a much better opponent (the great sandbag, bane of champions), as your ridiculous theory would imply, or is there something else going on, especially if the said champion keeps fighting normally after this sus incident?
This whole “There’s no kayfabe, jis’ git gud in da gym and raise yer MMR” mantra you… adepts keep adhering to is asinine.
You’re saying as if something like that had existed in the first place.
It seems you would presume that those people, including their nominal head, know or understand what they are doing. That already is a very strong assumption.
When you consider this, maybe hate gives way to some other feeling, like pity.
No, gotta hide it behind gacha gimmicks and con tricks… like the whole ‘pets’ shebang and all, you know.
Finally, somebody who understands at least the basics.
