Nothing about this change is to invalidate the fact that threat should matter and by extension that means when you co-tank a raid, working together matters. Not every tank specialization generates threat at the same pace as the next, so its a give and take and one where you must work together.
My comment about SM was more for Havoc specializations where you tend to have crazy burst windows with Eye Beam, trinket, and essence choices. As a tank, see above.
We shouldn’t, but its where we are.
I brought up in alpha that specific tank specializations have very skewed and too low threat modifiers on their toolkit, ability cooldown, and frequent use compared to other specializations, but that obviously fell on deaf ears.
I’ve never liked the threat-matters game-play as its always been super hard for Blizzard to balance in any meaningful way without either skewing tank damage too far to the extreme or cranking the threat modifiers to the moon and back to account for the disproportionate scaling damage specs get.
