What is the best class for PVP?

Hello everyone, I'm new to this game.

I've been reading a lot about the class combinations , many guides say Darkrunner , Paladin , Daggerspell , Shadowblade and blighter are the best classes. I don't know if it's true, but I want to know what is the best class for PVP.

Sorry if my English is bad, I am from Venezuela :o
