I would rather play another game with suppression mechanic and some weapon kick instead of a weapon bloom or meta laser guns. I would love to see the maps from BF2, 3, 4 with similar game flow. The next iteration in the series might bring back fully-fledged classes instead of cheesy and goofy specialists.
Please create a game dedicated to the younger generation and capitalize on it like BF: Heroes. But leave anything that starts as the main lineup in the series for adults. That would be the best solution for everyone, not even wallet-wise but preserve customers' sanity.
Do NOT remaster BF4 or the game will turn out to be yet another disappointment. Adjust a bit resolution in Full HD. The game becomes mint in quality at 140% resolution scale and at ultra settings.
