I have the English client.
If i type /console MSAAQuality 1,1 then in Game Menue -> System -> Advanced -> MSAA gets set from "None" to "Color 2x / Depth 4x"
From 0 to 3,1 it switches between the 8 possible Settings and i see the Anti-Aliasing Effect difference

But with /console ffxGlow 0 or 1 you were right. Didnt see it in Boralus, sorry. I had to go to old Darnassus to see it.
