A terrible decision that goes against the core of the game and continues in the vain of the widely criticised BF2042. Feedback on specialists in 2042 was given early on, it was ignored, then sales (or lack thereof) put pressure on the team to review and change to a quasi class based system. You are now starting from that quasi system and will fight tooth and nail, again, until you renege and implement it, somewhat, properly - I'll wait until that point, or not at all.
It IS gonna be the class system you just have an extra layer of choice on what to use with the training, which again is just the squad upgrade mechanic from BF4
The real issue is global weapon availability, and thats something that needs more conversation cause it dilutes class focus and creates very cheesy meta strats that self-remedy any real weaknesses.
Maybe something of a balancing act, but what if there were one or two of each type of weapon available to all classes, then the deeper/more specialized ones are available to just that class-type?
If theyre still going with it odds are theres no changing it, so we gotta find suggestions to mitigate OP combos like Irish Rorsch spammers with med/ammo bags.
Personally I think weapons should have a negative modifier if used outside your class. Youd suck with something that isnt your forte and that should reflect in game. RN my vote is to carry less ammo and handling is worse. Slower ADS speeds, perhaps worse recoil. Then so long as the guns themselves arent OP you have possible balance. ofc tho people will try to just snipe as medics to self heal and never help the team so theres that, but hey we can say we tried.
