Since I’ve made my usual mistake of reading the comments sections, here’s some bonus ranting.
No, the sample size is not too small. Yesterday used roughly 700k games. Today Dotabuff is at 1.4 million. There are other unavoidable issues that, while they do not invalidate this exercise, are still worth keeping in mind:
- Popularity Trends. Keeper of the Light was used in only 5.73% of 6.80 games. Yesterday he was used in 13.67%, the second largest net shift between patch rates after “Gonna Rush an Aghs” compatriot Lich. He has 169,804 games played in 6.81 and 104,202 Aghanim’s Scepters built, for a Scepter completion rate of over 60%. I do not believe these trends will hold, and when they stop holding it is likely they will alter his win rate.
- Unfamiliarity Driving Failure. As I mentioned, people in general do not yet understand how Tusk’s new snowball, Zeus’ Lightning Bolt vision, or Ursa’s itemization options. More time for knowledge to spread here will drive future shifts, not a mere increase in sample size.
- No Bracket/MMR information. Most of this is from Normal games because Normal games are the largest part of the distribution. Very High may be taking certain changes differently.
As for day-to-day noise, there’s no need to wonder about it as Dotabuff has already provided day-to-day win rate trends for every hero:
I also apparently need to blingee the heading “Small or Statistically Insignificant.” Complaining about mentioning Keeper of the Light in regards to 6.81 patch changes might be the single dumbest reddit comment I’ve ever triggered.
Also apparently Abaddon is bugged in 6.81 and receives the new Aghanim’s buff without actually buying an Aghanim’s. It certainly would help explain his unexpectedly high win rate increase.
