Received a question asking whether any heroes had a noticeable win rate advantage on either Radiant or Dire, so I threw this together. There’s not a lot that’s terribly interesting here to me, so I’ll present it mostly without comment. Keep in mind that the percentage differences we’re looking at here are fairly small, so most are likely well within the margin of error.
(Quick explanation on the expectation column: since Radiant has the higher win rate overall, it tends to have the higher win rate for most heroes. I just did a quick regression to see which heroes grew the most/least. There were a couple other ways I considered expressing this, and none of them had results that were much different than the others.)
Ursa is, unsurprisingly, the largest standout given his predilection towards Roshan. Beyond that who knows. I’m sure you’re all capable of coming up with your own theories, but I wouldn’t read too much into this and instantly demand Bloodseeker mid every time you’re on Radiant.
Also I looked at what heroes had the largest percentage of their games either on Radiant or Dire.
Medusa is the big mover here for Radiant ancient farming shenanigans. On the opposite end but to a much less degree we have Beastmaster for his Dire ancient stacks. Also of note, despite being the most successful hero on Dire, Ursa was one of the most popular Radiant picks.
But yeah, overall I’m not enthralled by any of this. However, if you are interested and want to look through the numbers yourself you can find them here.
