latency is certainly a huge issue with this game (and why SE thinks reduced cast times in some battles makes it "harder" is plain silly.) anyone with pings over 80ms is considered second class by raiders, and they will be seeing dps loss in the 10-20% range no matter how good they might get. One thing I did notice way back when I first started, is that if you're using a TV to display, the TV itself can be adding about .5 sec just with post/pre processing. check re your specific TV model, you should be able to turn that stuff off.
