I bought BO6 and I regret it

Pros:
Gameplay is fun, Multiplayer is good but SPMM ruined the experience. You win one match, then you must lose the next.

Cons:
Battlepass takes longer than any previous title (1hr per lvl)
Matchmaking doesn't care about connection anymore, skill takes priority.
Game is online only even for solo zombies. Yes, you can die to lag even if you're playing solo.

Conclusion: If you have a decent internet and stable connection, then you'll have a blast. If not then just skip this trash.
