Guys, please. For the love of god get your facts straight before going o about how it's all down to computer. I play on a four year old craptop that averages 10 FPS, but I can still win. It is not about who can click faster. At all.
Can still win against who? People with 5fps? If you lag, you're not going to be able to hit others. It's blindingly obvious that those with a better computer, and with a good skill at pvp WILL win against someone with 5-10fps
