If you want to be a master pvper make sure you have a fast computer good gear and alot of skill.
It takes a lot of practice to be good at something but your sure to get there.
The first thing you should do i set up a faction on any faction server.
The next thing is you should mine for at least a half an hour to get some good resources.
Then after that it goes down to potions and enchants on your weapons.
After that all there is is skill and alot of it so dont worry if u die you can try again it just takes time.

I hope this helped
