Ok i want to raise a few challenges to the things said so far:
1. Campers: the kill cam pretty much shows you exactly where they are, get killed by a camper once, its unfortunate, get killed by the same campers more than once, shame on you. I rarely come across campers on conquest, when i do, i deal with the with a few grenades to get them out their hole and then hose them down. Camping sniper? just whip out a sniper and pop his face off.
2. Being shot down without knowing in a heli: Yes at the start of every game the map loads on ps4 and no sound in vehicles is a bit annoying, however, how the FUCK do you get shot down straight away unless you playing something like Rush? i've never been shot down in the time it took for the sound to load because its hard to get to the enemy or target flag before the sound returns. Maybe try holding back a little longer then going forward.
3. Lag issues: with server browser i tend to search for games with either official EA server or games within my territory (EU). I don't tend to find many games at all with lag however i'm on ps4 version so may be different on ps3.
4. Getting killed by someone with 0-1% health or through impossible circumstances: i've had this numerous times where i've been killed and the kill cam shows a guy either the other side of the map, behind a wall or two that would never of been able to shoot you, or in a on a completely different height level than me which would not be possible to kill me, i believe this is a slight bug in the game where the killcam glitches and shows a DIFFERENT person to the one that actually killed you, if you look at the battle feed it might say [NGU]Resistthesun killed [SWAD]xNeo_Angelox but the killcam and killcam "killed by" might show a different person entirely. I think this has been pretty much fixed now, as i was one of those who was like "how the Fudge did i die? did he shoot through 100m thick concrete and kill me?"
The issue with the 0% and 1% healths i tend to find that they are near a medi-bag or have died and been revived after you died which shows them at 0% health. the bullet detection can be a little annoying as people said, i've had many a time where i've hosed a clip into an enemy with his back to me only to be gunned down in a few hits and him being on 7-15% health (basically one bullet away from death).
4. Freezing issues: Again this may be a ps3 issue, but i've never once had battlefield freeze on me while playing, the only thing that happens to me on ps4 is when you load up the game and press options to bring up the menus to select multiplayer, nothing comes up and you can't press anything however the game hasn't froze. You just have to close and re-open BF4.

OK now i've hopefully cleared a few things up i'll tell you my biggest annoyance with this game, how is it that my RPG's do fuck all damage with a direct impact yet i can be killed in one hit by an RPG that hit the ground probably 5 yards in front of me? it seems whenever i fire an RPG the blast radious is tiny, yet when enemies fire theirs (doesn't matter what RPG we are talking about here, same with n00b launchers too) they kill me in one.
An Example i have was on operation locker, i thought i'd roll with the XM8 n00b launcher (the one that locks to a range and explodes grenades as they are above that designated range), i fired an ENTIRE clip (5 n00b tubes) at this one guy, got a hit marker with EVERY ONE and i failed to kill him, he fires a SINGLE n00b tube from that other one (the one with the iron sight that looks like a ladder) and i died instantly, killcam shows him on 23% health. i have no explanation for this and it happens all the time, i got a direct impact hit with an RPG-7 and failed to do more than 55 damage to the enemy yet i got killed with one SMAW rocket.
