Since they seem to like to fix/change things that nobody complained about. What can we expect next?
How about make the size of the interface size fixed with nice big buttons? All those interface addons give advantages that casual players with no clue don't have. We need to fix that.
Damage parsing tools. They just make people compare and belittle people who have no clue. Let's remove all LUA commands that allow to check the combat log on the fly.
Bag addon tools - with Legion we get a bag sorting tool. People with bag addons don't see it and that's a shame. So let's remove addon functions that change the bags and how they are displayed.
Auction house addons. The casual user has no Tradeskill Master or Auctioneer addon - that gives people using those tools a clear advantage. Let's remove all the LUA functions making these tools possible!
Or we make a bigger step. How about disabling all addons? Then the game is the way the designers want it to be, not some "cheaters" that add new functions and features. Blizzard knows what's best and all quality of life addons are not needed anyway!
Any other suggestions what they could change people like and use for 10 years now and haven't complained about?
