why has activision left DMZ behind?

seriously dmz is a unique one of one game mode almost a different game,with its unique loot system,quests,the exfil mechanics,and its amazing mw2 casual movement, and the best map in history of cod AL Mazrah which is Giant has a crazy good vibe and the matches are much more tense then warzone seriously DMZ is so good so many crazy legendary moments can happen and with the gas and exfils its crazy fun and even better you are playing against skilled players all the time so its all about strategy and guns. Truly a masterpiece,they could have atleast made the anti cheat better because there is a insane amount of bugs and cheaters its unplayable like atleast 1 of 3 matches in ashika island or vondel are guaranteed to have a cheater.
