First they need to fix the core elements of Battlefield, otherwise you are patching and not solving the issue.
They need to rework the class and path system to be more balanced. They need to fix meta class (support) and pointless path (spec ops). I would prefer close weapons but a hybrid system would be welcomed and allow smokes to be open to all or at least recon
Map design is good but the sizes are very small which technically they said they'll release bigger maps on future content (annoyed that ill have to pay). But when creating big maps have a mix of areas (urban, open spaces, trenches and different elevations) with well spaced objectives would make maps more diverse and require different strategies to obtain them. More strategic and allow vehicles to make better use of its speed
Game pace needs to be more tactical. Increase respawn penalty so players will avoid zombie rushing or feel like team death match. Definitely agree with slowing movement, decreasing jump, and increasing penalty on movement mechanics (sprint + jump should be heavily penalized instead of rewarded)
Old Suppression should be brought back, slightly blur with a small AoE so you need to fire near the enemy to supress it. The health regen delay could be added as Suppression for explosives with a very wide and prolonged AoE as explosives feel rather useless. Also remove the glow from grenades, the old warning system is more then enough and this would make interceptor system more valuable to equip.
Agree with comments and post that there is plenty to fix and balance but if they would deal with these areas first, the game would truly feel more strategic and it would be easier to balance other areas
