Are they ever going to add a Mixed Category for quests again? If not, why did they take it out in the first place?

Inactivity mostly. People could pull east WRs for the sake of having them in their bio. And the screen player didn’t really do much. It was always one screen player and the rest were VR players. It won’t come back. (Cat Ext maybe but not for a long time and don’t count on it.

Cat extensions I doubt it would be more inactive than most of the cat extensions there already.

No.
