Making sense of your own performance and just basic stats with any given hero gets complicated. In part for that reason, I wouldn’t mind the suggestion you made in another thread to have games lost with an AFK recorded in orange.
My salt is why would a Diamond player draft Nova vs a Johanna/Rexxar/Cain/Jaina and Raynor? I mean she was last pick on Cursed Hollow, doesn’t take bribe and Triple Tapped the Sonya and Johanna at almost full health anytime it was off CD. 
*Oh Aphandra, it’s so strange seeing you sport a Tassadar Avatar!
