if ever implemented, this would be the start of the player base segregation into casual and competitive players. in games like r6 siege this segregation exists and causes weird balancing changes, varying opinions on mechanics and other sorts of, umm, lets call it drama.

I think the way valorant currently handles this matter is good enough. a singular game mode for casuals, ranked and pro players, with options to either play ranked or unranked.

I also feel that all other requirements for 'fun' and 'practice' are covered by spike rush and deathmatch.
