How to deal with warrior as sub rogue in pvp?

How do you deal with an arms warrior in pvp on patch 3.3.5 as a sub rogue? Arms warriors counter rogues already but is there anything that will help me beat them? Like what kind of moves I should open with or what kind of abilities to use in different situations? I know you need a lot of resilience vsing arms warriors but as a sub rogue you will need quite a bit of armor pen because they're plate.

Its as simple as not letting him rend you and or actually hit you, charge kite him bleed him and restealth as much as you can in his face. If you're good he wont be able to hit you at all and you'll chip him down eventually. You're a rogue play like the biggest ***** ever literally, its how your class is played and if anyone calls you out on it remind him that he probably sucks if he's saying that.
