Lag since .75 Patch?

Lag isn't exactly a glitch or a bug you know... More often than not it has either something to do with your own stuff, net, computer etc, or a temporary thing that occurs for some after patching, call it a connectivity issue. At any rate, imo, it's not something to report here, I'd point you to tech support if it was my call.

Tech Support is for individual issues.
As you can see, a lot of people have been having issues since the patch.
Plus, it isn't really a "resolvable" issue. It can't be supported by Technical /Support/.
