In a recent post on the official Battlefield 4 blog, developer DICE is asking for players' feedback on what they should balance next in the game. They have a lot of tweaks planned for upcoming patches, but are looking for help determining what players want next.
The blog post is a series of five "yes or no" polls that cover attack boats air defense, FGM-148 damage increase vs. tanks, stealth jet cannons, fast attack craft cannons and MBT and IFV Canister shells. DICE is still working on more than a half dozen issues that are plaguing players of the game as you can see on their BugTracker post.
