Can't make a move! What's going on

I’ve been playing halo for years and I have NEVER played this bad or have stats this low. Even on crazy MCC. Halo2 all the way up to halo 4 i had abpve average stats all around. idk if the mechanics of the game just isn’t my style or something is seriously off. I don’t get that zeal to go hard because the controls and game play just feel weird to me. Definitely a buzz kill
