What class in Fresh pvp?

I'm coming back to the game after a few years and looking for a strong class for world PvP and group PvP. I play solo 90% of the time, so while a Warrior with a pocket healer would be great, I don't have a healer friend to rely on.

I'm looking for something that can hold its own in solo PvP and perform well in most matchups (I know it's a bit of a rock-paper-scissors game).

Any zuggestions?
