When does the fun start?

I played the crap out of BF4 back in the day. Now retiring to what people are saying is the best current bf and I gotta be honest I’m not having any fun.

I’m looking for advice and complaining at the same time

I’m not getting any kills and I die at random from everyone direction no matter what I do.

My shots are like peas while I get torn asunder by the enemy with laser LmG accuracy. Like fr these enemy’s seem to know exactly where tf I am even while behide cover (I wasn’t spotted I check)

Not to mention random deaths in vehicles just when I actually get a kill or two.

I’ve tried slowing down my headspace but then the crack out bunny jumper comes in with a pistol versus my smg and I die.
