Here's some crazy ***, Diablo III has been experiencing lag spikes for the last season. Blizzard has been unable to figure out why till recently when they did a massive stress test PTR run.
It turns out their servers were being attacked by Barbarians.
I ***you not.
Quote:
The changes made to Whirlwind were not made because of concerns with balance. The changes to Whirlwind were made to improve server performance. Our server logs indicate that Whirlwind was a significant factor in server performance issues experienced by all players (even if there isn’t a Barbarian in your game). The intention is to improve server performance without affecting the power of Whirlwind.
We're currently discussing how we can get server performance gains without affecting the power level of Barbarians. This might mean reverting our optimizations, or it might mean providing alternative complementary options for Barbarians to compensate for the change. While we haven't made a decision yet, it's possible you'll see a couple iterations or different approaches throughout the PTR.
TL;DR Barbarians spamming one move was kinda DOSing their servers.
