Don’t understand what?
What you don’t understand is the it’s the spec that sucks and the weapon has no bearing on that at this point.
It’s not some overly complicated spec and never has been and it hasn’t changed much if any since the beginning of BFA other than Icecap being a thing now.
I think almost everyone is in agreement that the spec is trash. Why do you think I quit? Frost was so good that I couldn’t stand the excitement?
