The data collected is from the Overwatch API which is in-game data.
Now the data set is of course incomplete but will and always will collerlate to complete the data set.
Even tho things have changed a bit it still correlates
In this they say…
On Overbuff she has the highest winrate for Silver,Gold,Plat,Diamond,Masters and GM
- So still true and matches
On overbuff Kirko and Moria are… still in the bottom half. Moria has improved tho and Kirko isn’t dead last because of Lifeweaver
- So still matches somewhat.
On overbuff Ana, Kirko and mercy are all still the most picked supports
- So matches
Now don’t get me wrong some things in the article don’t match Overbuff now but it is an old article and things have changed since like…
Isn’t true now but he has been nerfed and you’d expect his win rate to decrease based on those nerfs which is reflected in Overbuff with him being 2-4th highest win rate tank now.
