Another atrocious thing in bo4 are the gunfight and weapon mechanics. I don't mean the wishy washy, destructive aa bubbles (you can't really blame game devs for optimizing a game for controllers) I mean all the no recoil guns, especially the lmgs.
What's worse than that, and this is one the main problems in that garbage game, is the insane hip fire accuracy.
You can run around with weapons like Auger, Rampart, Titan, Vkm - weapons that should be bad for cqc - and once you see an enemy in front of you in the range of 1m - 3m you can just spray n' pray the sh(%t out of him. From the first bullet on, all your shots are going to connect, even if you're under fire. The hipfire accuracy is beyond broken.
If you tried this in Bo3 with an ar or lmg, you would have missed 29 from 30 shots.
So they increased the ttk, which technically increases the skillgap, but in return they made the weapons incredible ez to use and added an aimbot for everyone.
Basically it doesn't matter if you're playing against "pros" or bots, every player only needs to press L2 + R2 and boom he lasers you with a 100% precision. Lame ^^
