(banner courtesy of /u/Somber99 Hello again! After each balance patch, I've taken it upon myself to track how the balance changes have affected the Nexus. It's become something of a habit for me, and I thought it might be fun to share my data with the community.In case you've forgotten what changed in the last patch, here's a link All data provided in this post was collected from Hotslogs , which is a database of player-submitted games. Data was collected between 3:30 PM and 4:30 PM EST each day, using the special filter "Last 7 Days (Current Build)". As usual, keep in mind that my numbers may differ slightly from Hotslogs's "official" figures as the site regularly updates older information as more games are added. Therefore, our data may not match up perfectly, but it should give a generally accurate view of how the week progressed. Here is a link to the spreadsheet with the data I've collected. The spreadsheet contains all of my original data, split into two categories: "Composite" (which represents all data across the entire week) and "Daily" (which represents data from each individual day). It also contains a number of graphs showing how each hero is performing in both win rate and popularity. If you'd prefer a summarized report, read on!Remember, only the heroes whose win rates are highlighted blue/orange with white text have exceeded their margin of error.Note that the error column assumes a 95% confidence interval. To put it simply, a 95% confidence interval is a numerical way to measure whether the win rate has changed in any significant way. If the change to a win rate exceeds the error, then we can assume that there is approximately a 95% chance that the win rate has changed.The seven-day analysis is below. Please note that while I try to cover all heroes, not all heroes are in need of in-depth analysis of their changes, so some heroes may have short summaries or may even be omitted entirely. Also, be aware that the contents of this section are primarily my own opinion of the changes, albeit backed with data. If you disagree, feel free to explain why in the comments below.Due to Hero League's lower overall pool size, it's hard to state affirmatively how much better she's gotten. However, as I had originally suggested to lower her trait cooldown in a previous analysis , I will still offer praise to the devs for making the decision to do so. It was, in my opinion, the correct change to make, and at least in my own experience, this change has helped improve her feel in battle quite a bit. There are similar doubts about the amount of true change as far as Cassia's win rate changes are concerned, with her win rate in Team League dropping off but no indications of a similar dive in Hero League, so it's hard to tell what (if anything) this might actually mean, or if it's simply a false positive.Her win rate has dropped quite a bit in both ranked settings, which is good as her previous standing was relatively unhealthy for an assassin hero. She retains her fairly strong and free clear, however, with no changes made to the explosion on Primal Grasp. This could still leave room for her to slide into the off-lane in the right conditions. Unfortunately, it's still unclear where her talent balance rests, as Hotslogs's figures seem to have had some problems that resulted in the loss of that information. With any luck, we'll be seeing more build variety now that the strongest options have been toned down, but we'll just have to wait and see!This is further evidence that making a variety of smaller tweaks across more heroes can be healthy for the game, as both healers have seen increases in win rate following the changes. Li Li now has a pretty high win rate, but I suspect it's largely excused due to the relative ease of her use and her drop-off in more competitive circles. Morales is likely to continue to struggle, however, in a meta that favors healers with anti-dive tools like those of Whitemane. Of course, like any healer, she retains her value in her specific niche.Whitemane received a slight reduction in health (a bit over 2%) and damage (roughly 5% to each ability), which in turn also weakens her healing output slightly. However, her built-in armor at Lvl 10 will likely keep her ahead in the race for healer supremacy in professional play. Tyrande received nerfs to Lunar Blaze which may help in culling her burst potential a bit as well. However, both healers are likely still the preferred choice for healing output and protection going into Blizzcon. We'll soon find out if that holds true!Looking for more of my work? My last HGC article focuses on Tyrande and the rise of double support. That article is located here.
