Berserker rage(immune to sap and gouge) and overpower(get rekt by an unavoidable yellow hit when you pop evasion) makes them dangerous for a rogue, but it's still a 50:50 fight and often comes down to which player has better gear and is better at character control and movement.
Most healers have trouble with arms warriors specifically, but especially priests, as cloth wearers who have only one distance opener that the warrior can become immune to.
That's all I can think of, but like others said warriors aren't a solo PvP class. Much like in PvE, their job isn't to do massive damage (but again much like PvE the potential is still there with the right gear), but to get the enemy to focus their attention on them while friendly dps does its job.
