It's crazy how COD has changed - it once was a casual shooter played at a steady pace where positioning and general gunplay were key factors to success along with a sense of awareness in the larger and less linear environments. Nowadays it's more of a sweatfest of sliding around on knees (even uphill on Cartel), bunnyhopping instead of walking/running, jumping around corners to screw the hitboxes, stimming in cover after being shot to shit, pre-aiming galore etc. The aggressive implementation of SBMM really kills a lot of the fun so if you do well, you get punished essentially. It's very hard to improve before you hit a brick wall and then likely get set back.
Treyarch have said that SBMM has been in every COD since the original Modern Warfare but that's total bullshit. I played in many varied lobbies in the original Black Ops and I know this because I used to look at leaderboards/combat records when the timer was counting down to see who to watch and which players were weaker. If SBMM was in the game, it didn't work very well that's for sure. There's is no way in hell it was in MW2 either. I really don't know why Treyarch push this so much especially when most people don't want to be playing in such a competitive-driven experience. It's sapped so much fun of the franchise this past gen.
Cold War may be boots on the ground and an 80's COD but it still feels like advanced movement with all the crazy stuff people can pull to get an upper hand on opponents, whether it be sliding or manipulating the lag compensation like we saw in BO4. The wonky animations in this game makes it hard enough as it is to track a player let alone if they are screwing the hitboxes through sliding, jumping or bunnyhoppiing. There is already enough artificial factors in the game which tamper with how your connection appears let alone other players being able to make it worse.
This game would be so much better if it was built from an entirely casual standpoint where connection is prioritised with no lag comp nonsense. Jumping needs more weight and consequence and sliding really should be nerfed or taken out of the game. I've been shot at dick-level so many times by someone sliding themselves into me (this line will be in the out of context thread guaranteed) At least the dolphin dive was more of a gimmick and not a huge aspect of the core gameplay. The old COD's really nailed the mechanics I feel and everything was technically spot on particularly in the classic Modern Warfare days. Treyarch always seem to go against the grain these days.
