There's nothing to fix. Game is rotten in its core.
It's ain't no BF4 man. Bugs and mediocre graphics is not a big deal. Game is a bad Battlefield game, that's it. BF4 was great even with missing textures on PS3 during closed beta.
No amount of bug fixing can fix the game's core. Polished turd is still a turd no matter how shiny it is.
If you want BF4 like experience play BF4, if you want something similar but new, look elsewhere, there is nothing to see in the New BF.
