1st Option : So basically all you do is play heroes that get high KDA and don't give a ***** about winning. All you do is get really high hero damage and KDA.

This guy plays like a 3k player but spams ult every time it's off CD as zeus, uses spells to killsteal and tries his best not to die.
He has 35% winrate as zeus and 44% overall but plays in the 5k+ bracket because he abuses KDA and hero damage.
death rating if you want high calibrated MMR just play zeus and spam your r key and lose without dying, you'll be 5k!
