Medic deserves its own separate role in BF6
I know the BF3/4 class system is popular with many folks here, but there were also problems that came up with combining the Assault and Medic roles into one.
Lots of players would choose the Assault class just for access to the best guns (ARs), and would then either not equip any med items, have them equipped and never use them, or only use them on themselves.
Sure there were exceptions who would play as true class medics, but that was not usually the norm like it should have been.
Medic needs to have a specialized role on the battlefield in the same way Engineer or Recon does. Once you start diluting that role and adding other distractions, players begin using the overall kit less effectively.
My suggestion: make Support the fully-focused medic role and give Assault the ammo packs and light demolition gear. That’s a pretty minor tweak from the BF3/4 system and still allows each class to have a more clearly defined niche.
