I keep hearing how Warrior has the smoothest leveling but I feel like I'm doing something wrong.
I use what everyone does Rolling Slam + Boneshatter and Perfect Strike on the bosses. I have to roll around to juke like >5 white mobs because if they surround me my health is gone before I get off one slam. Playing like a pussy and running away with sunder seems to get me better results. Even the boss damage is whatever.
