I actually posted that exact thread/blue post in the other thread where I was talking about this, but according to some warrior posts I’ve seen recently that claimed to have tested it, it’s splitting threat between the number of enemies currently. I don’t actually play a warrior in classic to test it myself, but any classic warriors that can confirm/deny would be great.
There were also people arguing in the other thread that it is supposed to split threat like any other buff and interpreted the blue post to be talking about a different issue.
Since people were using Bshout in raids in actual vanilla to hold numerous adds over AoE spam it seems obvious that it didn’t split threat in 1.12 since if it did it wouldn’t be able to hold that many adds over AoE damage and also wouldn’t require a nerf in 2.0.1.
The other thread was about druids which is why I decided to ask in this thread instead since it was kind of off topic for that thread (Is it just me or are druids the best 5 man tank in the game?).
