The essential skills to PvP are Rush, Crazy Standing, and Order Swing. There is very little we can tell any Guardian to help them improve in PvP other than practice. There is much more to being a successful Guardian in PvP, but as you play you must learn through your own experiences how to play your character well. We got plenty of advice from a fellow Guardian in our guild, but none of it was of any use to us until we were able to go PvP every day against a rival guild.
The best piece of advice we can give is to know your opponent. It is useless to go after somebody who you hit 4's on, so if you are out-matched you can simply help out in group PvP with your stuns, War Cry, and Heavy Weapon Rohan Gold instead of being a main killer. Otherwise, just go after the people you know you can kill within a single rush or help stack stuns on more powerful players in order to drop them with a team effort.
The most important thing to remember about your character is that this game is based around group PvP. If you are into duels, you can build your character that way. All we are trying to say is do not look at a build and come up with a billion counters to it and then think it sucks because the truth is, half of it is just theory anyway. We see people in other forums question certain aspects of builds because of the 7 million counters to a certain but that's why this game is balanced. Any build is countered and it's important to play your character to its strengths and not its weaknesses.
