This is what Blizzard is trying to tell to all the complainers:
Class Balance
- Raids and Mythic+ dungeons are the content people care about balance most for and they aren't available yet
- Outside of balance tweaks, there are mechanical tweaks the team wants to make to improve gameplay. You won't see these via hotfixes, but should see them in Patch 7.1
- Balance isn't perfect right now, the team is working on it, but there are lots of different variables
Artifact Power from PvP
- The team is looking at Artifact Power gains and will make sure there aren't huge imbalances
- The team started out conservatively with Artifact Power in PvP because it is easy to spam skirmishes
- hen rated PvP starts again you will be able to earn more Artifact Power
- PvP players should be able to level their Artifact through PvP
I'll warn you again: PvP is over. They gave full priority to PvE course of e-sports failure.
