@Kunstula The engineer/support weapon proficiencies are not a bug.
2042's support class primarily revives, and giving ammo (or medkits) is a loadout choice. It's not the dedicated ammo bag class anymore. SMGs make sense. People are dead near enemies and you have to sprint. Giving the class formerly with infinite ammo the guns with 400-600 bullets and an RPM of something like 600, instead of the ones that have 180 and an RPM of 1200 never made a lot of sense anyways. The kit anti-complimented itself.
Engineers most likely got LMGs because it's the remaining weapon category that made most sense. Engineers aren't particularly complimented by SMGs or PDWs or whatever else, they can shoot rockets at vehicles from decently far away.
@KunstulaIt's not a bug. Here's the patch notes in which the weapon proficiencies were introduced: https://www.ea.com/en-gb/games/battlefield/battlefield-2042/news/battlefield-2042-update-notes-3-2-0 where you can see each proficiency outlined.
The reasoning is "speculation". It's what makes sense since support can drop both ammo and medkits, and is primarily focused on reviving. In BFV, the reviving class had SMGs. In BFH, BF4, BF3, the reviving class had assault rifles. Reviving classes shoot people around their subjects.
Ammo with LMGs isn't a balance problem, it's more of a boring problem.
