MCC translating terrible!!!

I am a player from an Asia country. In Asia Halo isn’t popular like it in The US but still have a lot of crazy fans(yes! it’s one of the best FPS isn’t it!) So 343i shouldn’t offer us such terrible translated game.Every Asia player I know(China Japan Korea) are complaining MCC’s terrible translate.
Main translate problem are shown on such place:
1,Subtitles do not match voice
2,Most lines may translate by AI,they looks mess and difficult to understand.
3,Some places don’t have a translated one(like maps name and description, Introduction to multiplayer mode,Terminal)
