How was your day today? - DotA 2 Edition

What is this? I did nothing but mismicro the whole game and it's still high skill. Where do they get it?
And the ones that say very high skill... how?

It's match-making bracket based AFAIK.

Also i had to give up on zeus as my daily hero, he used to be one of my best heroes but 5 losses in a row X_X
