Class that is best suited for PvP?

Definetely Shaman is best suited for pvp. My favourite battleground is definetely alterac as well. Its a big place and got many npc's to harass...hehe. Try going solo into their camp and kill their boss. Haha i dont think so hehe. All lvl 60+ elites.

I think that depends of which one you know how to use the best...but in my opinion, warlocks are the ownage.

A lot of PVP played now is battle arenas so pvp has changed a little. Theres nowhere to run really and you gotta fight, u can't just dot sumthing up and run. Something that can crowd control or self heal is always useful. Shadow Priest can kick out good damage and heal when they need while Paladins are an absolute pain to kill, they just never die! A mage is pretty good in arenas though as you can sheep ure targets and reduce the enemies dmg potential. But at the end of the day the player makes the character what it is, not the other way around.

I think rogues are the best class for the battle grounds. In 2v2 areans.... a shadow priest and a warlock are impossible to beat.

Although im a mage...i can still own hordies =D
