BF4 issues I experience regularly.
- The dumb camera shake glitch makes you feel like you are in a michael bay movie
- The delayed reaction kills
- Getting killed in one hit by an assault rifle firing from well over 200m away and you have full health
- being knifed by people that are already dead (one time a guy detonated a claymore as he went in to knife me, he died and still got the knife kill)
- excessive rubber banding
- dying for no reason whatsoever, usually the kill feed shows i committed suicide
- the annoying "kill trade" which almost never happens in bf3 always happens in bf4
- the kick to xmb
- the spawning outside boundaries on golmud railway (it's really ridiculous)
- getting killed around a corner. not by grenades, usually by a pistol
- the c4 bouncing off vehicles (i throw it and witness it hit the vehicle and bounce off in a random direction usually next to me, happens too much with helicopters that hover low enough)
- you see the shot land, head shot, it must have been, guy is lying down only part you can get is head, blood spattered and everything, but no hit marker, and when he dies seconds later, no assist, not even a suppression. lucky if you get the spot bonus though.
- commander missile killing you when you are inside an impenetrable building.
- jets ramming a helicopter, destroys the heli, jet survives with nary a scratch
- Killed in action, for all air deaths, no indication who killed you or what.
- The strange friendly fire screen when you are killed by an enemy.
So far thats all i can remember.
