Why are you guys so hellbent on turning this into a “lol PvE raiders wants nerfs” thread?
Seriously.
I remember back in MC someone bringing up a combat log for Golemagg where he just double tapped their Tank and there weren’t any Parries nearby. No one could really figure out what was going on because nothing indicated why he would suddenly smash two rapid fire autos, but since it was just Golemagg, no one really investigated further.
With the dramatic reduction of spell batching, one thing I was looking forward to in Naxx was no longer going from 100-0 and seeing 4+ attacks land on the log, alongside 3-4 heals, but I die anyway because of batching. Incoming damage is a lot smoother now because you aren’t getting sudden random bursts of 7-9k that also ignore your incoming healing because the game still thought you were full health. But with that increased smoothness is the much more recognizable double hits that shouldn’t be happening in the absence of some kind of hidden thrash/flurry mechanic.
I have no desire to remove the ability, as no one else is saying to do so either. Rather, understanding how and why it happens (low CD? mild proc chance?) so you can plan around it is all that is needed.
