What am i missing?

Ok,general question.I consider myself an average player,usually top 10 and from time to time finishing the game leading the scoreboard.216 atm.But for a few days now BF6 started to get really frustrating.Im loosing almost every gunfight,no matter if close range or an a distance.Im getting hit and killed from almost impossible situations and places.Evrey gun im using,i can't get along with.Nothing suits my playstyle anymore,wich depends on class is ether aggressive or supportive.

Did I miss something?I know the game had an recent update,but dude.Every match feels like an Cronos Lobby atm.

So yeah,pls help me out or roast the shit out of me.
