I don’t even know how to start to describe what this nerf is.
First, they developed this tier bonus and have never considered how much the damage output from a blood DK could scale. And we aren’t even 3 months into the season.
Now the Nerf does not only affects the damage output, which doesn’t really address the problem (the strength bonus stacking). The bonus should’ve been capped to limit the damage output.
Now, reducing the 2p bonus from 0.5 to 0.33 will reduce roughly 30% DRW uptime. That will probably reduce the damage output but at same time it knocks Blood DKs to the bottom, and we’re suddenly back to season 1. If this change is not reverted until you can actually come up with a more proper nerf to address the damage output (cap the Endless Rune Waltz stack from the 2p tier) without drastically reducing the survivability (and at same time, the viability) of the Blood DK, I believe that you’ll start seeing a huge reduction of Blood DKs in high keys (and guilds raiding Mythic right now having to gear another tank to replace their Blood DK they invested so hard).
