BRs Need To Be Changed In Enlisted

Ive been playing for a couple months on Germany when i unlocked the MG42 i kept on getting uptiered to tier 5. This might not seem like a major problem but after that all grinding all i fought was decked out AR squads while still only having semi autos.Personally I think Br5 needs to be its own thing cause you do this grind only to fight Jets and Ars which is completly unfair
