It's crazy. That's literally all it takes. That's how incredible 3, 4 and I've even throw in bad company two areDICE has done it properly with BF3 and BF4.
They just add unnecessary innovations with every new game and deviate from their OG blueprint for a successful BF game. Ex. Operations, Firestorm, Hazard Zone, Specialists, etc etc.
They also release their games 1-2 years too early (BF4 included).
If the next BF game is just a BF3 and BF4 clone with better graphics w/ BC2 destruction and BFV movement then they got a classic on their hands
