I haven't noticed much. But there have been complaints in the past that players die too quickly from gunshots. So maybe that's what we" re seeing.
Even headshots in real life dont kill 100% of the time.
On a news cast, I've seen where someone gets shot straight through the chest and doesn't even realize until 10 seconds after. And dies around 10 min, later.
If there was a change in the patch, maybe its better?
