I miss the:
- connection (still was better than Ghosts for me)
- Longer ttk
- Sticks n stones
- Smaller maps
- Nuketown
- The community
- Colour scheme, not bland and gray like Ghosts
- Lack of hackers
- Fast invites and joining
- Fast paced
- Large playlists
- Decent game modes like Demo, Hardpoint etc
- Scorestreaks
- Objective focused players for the majority
