Battlefront built to much like Battlefield now, and Battlefield hasn't been good since the 2nd game. To many people and not enough competitiveness for me. I didn't mind the beta, but not a game I would spend 60 for. I am really like Bo3 so far, it is pretty balanced except for one LMG. Soon as the severs get stable when the population of people playing starts to level up I think I will be putting a lot of time into Bo3.
There is level system for all three modes, which you can earn skins for your characters, emblems, calling cards. Also the specialist have gear you can unlock by just getting kills. They fixed the supply drop to not have effect on game and be all hidden skins for, as well you unlock these drops every 10 or 30 kryptokeys you get by just playing. Dead Ops 2 is back, you access in SP through the safe house. SP is 4 player coop they added a realistic difficulty which one shot and your dead.
And for what its worth it all is working with very little bugs and balanced.
