i play an immortal spec jugg. i have no issues tanking in pvp, but it does become way easier once you get to the higher levels and more abilities are available to you. Then you learn to use the resolve bar and gg, because now you know when to use cc and use your cc breaker. i absolutely love tanking in pvp now especially the difference in game play going from 39-40 and cant wait to hit 50 to get all my skills and redo my button ui config for pvp.
