And just an idea: Add an option to disable WoD, Legion or BfA completely. When I'm somewhere in the BfA regions I will get a lot (normally more then 20) quests and missions with money, toys etc. from Legion. I can disable most of these things from the menu, but only on a per item basis. What I would like to see is a button I can press and then it only shows BfA content. And when I'm somewhere in the Legion part, I can disable BfA and enable Legion, so I can see what is relevant there now.
