So Zul’jin took a hit to his winrates a couple months back, and I wasn’t sure why. He hadn’t received any patches recently, but his ~52% winrate dropped to around 48% (4% is a pretty sizeable drop) and has remained there since. I guessed it may have just been a shift in the meta, but that’s all I could think of.
Well, I think I may have just figured out why that happened.
When I was doing some math for another thread, I noticed that the HotS wiki now states that Grievous Throw’s bonus damage stacks additively with other attack damage modifiers applied to Zul’jin.
Previously, Grievous Throw seemed to act much like a negative armor effect, causing the target to take 50% more damage from Zul’jin’s AAs even as Zul’jin’s AA damage remained the same. This meant that Zul’jin’s self-applied +25% damage from Berserker stacked multiplicatively with Grievous Throw’s +50% bonus damage, totaling an 87.5% damage bonus.
Apparently, Grievous Throw’s damage modifier is now considered “self-applied,” meaning it now works like a damage boost to Zul’jin himself rather than a “vulnerability” effect on the target. This despite the fact that the ability’s tooltip still reads, “Marked enemies take 50% more damage,” which would imply the effect is applied to enemies rather than Zul’jin.
This means they no longer stack multiplicatively, only additively, reducing the damage bonus from pairing them together from 87.5% to only 75%.
In the past I confirmed that Berserker and Grievous Throw stacked multiplicatively using Try-Mode, back before his winrate drop.
When I tested it out today, I confirmed that they no longer do.
Perhaps this was a “bug” the devs fixed at some point but didn’t include in the patchnotes?
Regardless, it’s quite annoying, because that removes most of the synergy between Berserker and Grievous Throw and undermines one of my best tips for playing Zul’jin, which is to always have Berserker on while attacking someone marked by Grievous Throw.
Fortunately, I’ve confirmed that YWA? still does stack multiplicatively with Berserker and Grievous Throw.
Tl;dr: Grievous Throw and Berserker’s active effect used to stack multiplicatively with each other, and now they don’t. I’m a little annoyed by that, and suspect that may be the culprit for his ~4% winrate drop a while back.
