You can simply disable a client lol. Tucker does hack. I was on an alt yesterday and he was hacking OD on kitpvp.
Not at all lol, a lot of amazing pvpers live in different regions of the world. Also some people are so good they beat people with a crap computer..
Eh that depends. My old computer was crap and I was pretty good but when you freeze you can't pvp so depends how bad the computer is. I now use my brother's computer which is a bit better (No more 2 chunks crap), now I don't freeze and I think I'm safe to say I'm good at pvp. All this to say that it depends on how good your computer is.
I guarantee you, if someone has 1-50 ms, they'll beat someone who's good even if they're not too good their self.
Yes I have LOL, remember on kohi? You beat me on mv cause your godly ping skuxxx anyways your good not to bad, compared to other ;]
