here IS how I’d like Blizzard to help U.S. w/ such issues, IF ‘all else fails’, while gaming. Why doesn’t someone do something like THIS? (found in this link)

"if you want the optimal online gaming experience, go to Advanced tab of your Ethernet adapter settings, and disable the following:
- Interrupt Moderation - clumps packets together and sends them as a batch - the main offender
- Flow Control - sounds counterintuitive to disable it, but it messes with existing flow control in Windows networking stack
- Receive Side Scaling - also messes with Windows networking stack
- [anything goes here] Checksum Offload - supposed to speed up performance by offloading TCP/UDP checksumming to hardware; in reality does nothing for an average desktop PC except interfere with Windows networking stack
- Green Ethernet - performance-eating eco garbage
Try it and see! Less rubberbanding zombies in Left4Dead, more headshots in your favorite FPS, etc etc.
Also, if you play a MMORPG and want faster responsiveness, you need to disable TCP/IP Nagle algorithm in Windows. There are multiple guides about it though.
