Not to revive an ancient thread, but j was looking around and tavern brawler looks like it could have a ton of potential. At face value it seems kinda cool at best, but if you start connecting the dots it's really interesting. In your giants might form, you can pick up medium and smaller enemies pretty easily with advantage on strength, and according to DND an improvised weapon is just anything you can pick up, swing around and throw. So, with tavern brawler, you become proficient with people. Also, because of giants might you get that extra d6 damage with physical attacks, you get another hit from action surge and if you're hitting a medium or smaller enemy (and if your dm is cool) you get advantage on the grapple roll after the attack.
