I fail to see how the lag is a major issue, but maybe its the system i run.
I don't get any general lag but just the hourly/half-hourly lag spikes that seem to effect everyone.
Theres 2 ways around that....
A) keep clicking, keep picking up/punching/shooting/running etc and the game catches up and usually registers your actions after 1 or 2 min or so and plays out in super-fast-time
B) Log out, log in. watch the stopwatch on the loading screen and you'll be in game a little faster than option A but of course without any super-fast-time catch up.
