TTK and TTD

I wanted to discuss the TTK and TTD, which in my opinion are very low in a game like Battlefield, very similar to COD's TTK, the inability to return fire or even disengage, heal, and re-engage (which is possible in other BF games like BF4/3) its very annoying. 

I don't know if this post will be heard or discussed, but what I would like to propose is to decrease the TTK from 3/4 shots to 4/5 to kill a person, putting an amplifier of x2.5 when hitting the head, which at the moment doesn't make sense as the TTK at the chest is too fast anyway.
