Overlooked combat issues

Rockets against infantry from any shoulder mounted launcher are absolutely abysmal in regards to their damage dealt. There doesn't seem to be any headshot multiplier for classes below sniper meaning that it takes 1 less shot to kill in the head vs the body. All 25 damage weapons have this issue. LMG are being out classed by carbines, smg and pistols in TTK performance at ranges that should be punishing to engage at. The overall precision of the LMG class weapon is no where near indicative of what they operate as in real life and they're nearly pointless to use besides not having to reload as often. I hope you see this, I've been a battlefield fan since bad company and I love dice as a creative company but BF hasn't been nearly as good as it was with BF3 and BF 4.
