You’re reading the points…but reaching a very different conclusion. The sum total benefit of MMR is… nothing. It makes no sense and serves no purpose. SR is already kinda wonky,
And as for tying it to your APM …that’s an equally useless metric. It’s been proven over and over again that it doesn’t actually improve your gameplay - even in RTS games, there are relatively low APM players competing at the highest level…using strategy. And Overwatch is nothing like that - why would a Reinhardt need a high APM? It makes no logical sense.
