Tracks Blizzard employees across various accounts.
I made a graph showing who beat who in HGC EU and NA respectively

This is purely based on league play, so excluding the Western Clash. I also omitted some lines for clarity -- if a team is higher up than another team and there is no direct line between them, that implies that the higher team beat the lower one.
EDIT: Fixed a minor mistake, thanks to /u/Progression28 for pointing it out
