General DiscussionHow exactly is hero ranking calculated?

I assume there must be more to it than what it said on the page about the new hero rankings, because I went 19-0-14 as TA and lost 9 points. I farmed well mid, got kills. Just wondering what I'm doing wrong for my score to go down by pubstomping.

I even lived with under 50 hp a few times with good usage of spells/jukes. *shrug*
