Few class balance concerns...

I agree with there needing to be distinct roles, but tbh even back in the day people only really played certain classes for the weapons not the roles. Players tend to kinda be selfish with their playstyles. Like tbh I will try to focus vehicles with a soflam or rockets when I can but then you see there be like a dozen other engies and they're all doing... nothing so the team gets rolled over in every sense. Can't trust a blueberry medic whatsoever. Players just wanna do THEIR thing (often trying to go for flashy/multiple kills) instead of whatever the team needs.

That said allowing medics to have access to snipers so they can just use a medbox to perpetually heal themselves is the most frustrating thing in this game, especially the Irish players who get to even stack up cover for maximum cheese. 

I hope BF6 goes back to this

Personally, I don't want any restrictions on weapons. I just don't want to go back to being forced to play a certain class, just because I want to use a particular type of weapon. I also don't believe that locking weapons to classes will do very much to encourage teamplay. 

I do, however, agree with point #3 that there should be Support and Medic classes rather than being combined.
