I only played just a few hours in beta 6, so I didn't even get high enough level to do any warfronts, so I'm pretty lost when it comes to what is good in PvP.

I would like to play a ranged class with high burst damage and solid defensive cooldowns (ala frost mage from WoW). Any suggestions? Doesn't necessarily have to be a caster; I don't know much about the "hunter"-type classes in this game.
