Default cursors looks blurry and pixelated on 4k screen resolution. Would be great to have an ability to not only replace cursor texture, but change it's size and scale too separately to UI scale.
It was always strange for me why Horde and Alliance default cursors looks the same, wouldn't it be awesome to have ones depending on race or armour class and gender.
With third-party programs like "YoloMouse" you will just overlay the game cursor (appearance) but it is definitely not a clean solution for WoW at least not in its function.
