I have a crap internet connection (roughly 200kbps sometimes downloads hit in the high 300's), and my PC is good but not amazing with the recent Intel CPUs and newer GPUs released since I built my PC. I've never seen any of this...
Maybe it's because I'm closer to Asia? I dunno.
I've had the first hit take a second to register, but never issues with a mob not looking dead when it is except when I've actually lagged out and started to R0
