My pvp sub rogue dont have dmg

Hello guys a really strugling with my rogue. I have bis PVE weapons heavens falls and lungbreaker both hc, sts hc and wfs hc. Rest of build is full pvp 2/5wf, rest rele. rele/wf off parts. ICC rep ring, second wf and i fell like i just dont have dmg.. only clases i can hurt are rogues and and some clothes. when i see warr/pala/dks i run away really fast.

Even if I have perfect scenario, when i do everything perfect iam able to do these plates to 60%hp then iam dead.Discos laugh at me because i cant even look at them.
My question is = do i need PVE offparts to be able hurt these 1k + resil mfkers ? Maybe i can buy ikurus chest and crafted legs and shoes. Also have pve belt vengeful nose in bag.
Thanks

Update : I noticed that some rogues playing with full pvp gear but they are like walking stunners in bgs then they are useless lol, pvp set with pve off parts dealing some dmg to healers etc. in back line but still think rogues are so useless in bgs. Also whey we are more than 2rogues in bg, ppl start leaving and blame us "rogues are useless".Also farming hks is rly hard as rogue, have also alt disco priest and its so much faster, just shield everyone and collect hks..never more rogue. Already on sale "sumbarks" buy it and end my misery please lol

Rogue is the best class by far. you get to choose who to kill. why would you bother play rogue in bg ? rogues is a specialist one shot-killer. to enjoy rogue, you need two things : one, gear. pvp gear is meh. pve hc is better. you already have so much control with blind/cheap shot sap vanish etc. why stack resilience ?
two you need a target. preferably a loner wich is not fully armored or magically protected. prey on the weak remember?
to farm hks i would do wintergrasp and world pvp. not bgs

Don't get me wrong but you are bad with rogue, I've seen rogues defeating any class that are skilled in PvP, you just need to know how to play it.

Classes that rely on physical damage need pve pieces with arpen to be able to do reasonable numbers on plates.

Best advice is to just play to Rogue's strengths as a class and pick your fight wisely, what I like to do with my rogue on TBC (different expansion I know but the principle still applies) is find the weakest link and farm them on repeat, that or always make any 1v1 I see into a gank, Rogue CC is still one of the strongest of any class and even a underpowered rogue can get **** done by being so obnoxious with their CC that they make it unplayable for the opposition
