I'll start with the lie. They said that they would not make any big changes to classes in the expansion. This is due to the artifacts.
But what did they decide to do? Nerf hunters aim shot nerf mage pyroblast. Buff frost buff arcane buff fury warriors. All of these changes may seem minor to you but they influence dps.
Now what are we supposed to do? Arcane is now better than fire. What's that? You already sank thousands of artifact power into fire ? Too bad.
You have a legendary that is tied to that spec and you want to change specs? Too bad.
What gets me is that these nerfs are unwarranted.what if some of us play specs based on how well they perform?
If artifacts are locked behind massive time gates like this then there shouldn't be any changes to classes at all.
