Odd player training people..

[viasta]

Ok, so I am playing my new mage in Epith and just shooting my bolts at imps. Then this lv20+ fighter won't stop ksing, so I asked him kindly, to stop, saying "please stop ksing me, thanks" BUT...He still didn't stop, so I asked again. Then he whispered me to stfu and quit Fiesta, etc. just non-stop flaming, then he divided to mock all the speedy slimes, like 6+ and trained me, killing me and many other players. Then he whispered me again, and said I am a noob and got killed by low level mobs. So I blocked him and never seen him again.
Why are there so many rude yet retarded players in US Fiesta?! GAH!!1!!1!
