1) Improve Lag Compensation
Lag compensation has been a part of the Call of Duty franchise for as long as the series has been online, and as long as players continue to join online sessions with different connection speeds, lag compensation will be a necessary evil for Call of Duty: Ghosts. Still, a new engine should provide the tools necessary to make strides with high quality online play. Call of Duty: Ghosts should provide multiplayer that doesn't favor good or bad connections and instead rewards players for good tactics and skills while continuing to make the game one of the most played first-person shooters around.
2) Fun Cooperative Mode
Infinity Ward introduced Spec Ops cooperative multiplayer mode in Call of Duty: Modern Warfare 2 and added some new content to the mode in Call of Duty: Modern Warfare 3. The team didn't reveal a similar mode for Call of Duty: Ghosts, but the new Squads mode looks promising and allows players to team up and take on AI enemies. The development team noted the game mode would have advanced AI that would replicate behavior of online players including drop shots, jumping around corners, camping and more. Whether this will make playing against computer controlled opponents fun or not remains to be seen, but if the enemies play the right way and the game offers players incentive to play the new game mode, Squads could be a great new mode for the franchise that could surpass Spec Ops mode as second best cooperative mode behind Treyarch's Zombies.
3) Multiple Endings Worth Seeing
Call of Duty: Black Ops 2 offered a branching storyline and numerous decisions that would change how the game's campaign would play out including two different endings. Unfortunately, one of the endings was completely horrible and not up to the same quality of the other ending and the better endings from the series' past. The new innovation in the Call of Duty single player experience is definitely an improvement for the series, but we'd like both the good and bad ending to be rewarding for players that have spent hours shooting their way through the game's campaign and not leave a lasting impression that makes the storyline not nearly as memorable as it should be.
4) More Destructible Environments and Map Changing Events
Call of Duty: Ghosts will incorporate more interactive levels, map changing events and destructible items that the series has ever seen. It's rare to find anything worth interacting with in Call of Duty maps from the current generation, but even the few maps featured at the Call of Duty: Ghosts multiplayer reveal event showed something neat that could happen in each stage, whether initiated by players or not. falling debris, aerial attacks and explosions can cause drastic changes to the layout of a map and provide some of the most exciting moments during players' first matches in multiplayer for Call of Duty: Ghosts, and we're hoping nearly every map in the game will have some sort of cool interaction that makes each worth playing when given the chance in online sessions.
5) Better Balance Between Class Items
Call of Duty: Black Ops 2 has probably done the best job of balancing its weapons to provide a good experience for players no matter what their playstyle is. Call of Duty: Ghosts should continue to see the same weapon balance that allows different guns having different benefits over others while managing to keep any gun from being too overpowered. Hopefully, quick scoping, no scopes and other related exploits will be removed from the game as well, though some players will inevitably find new ways to gain unfair advantages in Call of Duty: Ghosts multiplayer. The team recently revealed some changes to create a class in the game too, so the freedom to create a custom class should be limited enough to provide equal opportunities to use whatever perks and equipment are available in the game without feeling restricted to carry certain items on every class.
