This game is actually near unplayable for me on my regular decent connection. I have 20-30 ping, and zero network icons 99% of the time I play. But everything kills me instantly. Yet I haven't heard anything being about it anymore.
From what I've noticed the game basically saves up damage up until the last bullet and gives it to me all at once so I stand around getting damaged like an idiot, but I don't know it. For instance, MG-42s drop me like a bolt-action headshot, not exaggerating, and even Recon SLRs kill me faster than I can react. Instead of (shot)--(shot) I experience (shot)(shot) with a microsecond of delay between bullets hitting me.
This is extremely frustrating. I can kill normally and I know how long it takes to kill with each type of weapon, so dying to the same weapons INSTANTLY is very noticeable.
