Half Point Monsters?

A fan points to a new “bug” that’s actually beneficial to players.

100% of my games in the past week or two have had a weird bug happening. i’ve noticed that about every 1 in 5 mobs i run into already has part of their hp reduced before i even attack them. i’ve had many friends notice the same thing too. anyone else noticing this? any idea why/how this is happening? and has blizz commented on the issue?
Grimiku: Thank you for posting about this! We’ve also noticed this issue while we were playing and looked into it. We found there was a bug (mostly with Monster Power) where monster hit points were not always scaling correctly when they spawned and resulted in creatures running around with less than maximum health without anyone or anything having damaged them. We plan to fix this issue in a future patch, but since it’s not a critical bug we don’t have an ETA to share just yet.

Have you guys seen this? I haven’t noticed, but my MP+ play has been almost entirely with a Demon Hunter, so I’m damaging things long before I hover to see their hit points, and hardly ever actually hover on anything other than the last boss in a group. In fact, as I think about it, hardly any Diablo 3 classes or builds actually target the enemies before attacking. Certainly not Wizards or Witch Doctors, and even most Barbs are just playing ridiculous “run past and kill them with dust devils” style these days. Which leaves um… well just Monks, I guess?

So, any complaints about Bliz being slow to fix a bug that’s beneficial to players? Or is it just the “bad” bugs that the haters come out to condemn with vitriol?
