I still think it's lag.
I was fighting a plane last night and shot it enough to kill it at least 4 times.
It shoulda died the 1st burst.
The SECOND burst for SURE woulda killed it.
The 3rd just ticked me off.
The 4th it just got dumb, and I quit trying.
A short bit later, all those packets finally caught up to the guy I shot up and BOOM they died.
From the first burst, to them going BOOM was probably 30-45 seconds at least.
I WILL agree that some "odd" things have been happening recently. I have noticed that my 1st burst, that USED To kill them, isn't. (not always, just sometimes, and with more and more frequency) I have to light them up twice to kill them.
Again, not always, and it's the exception as opposed to the norm, but out of say 100 kills, a good 10-15 had to be killed "twice" to be shot down.
