I started playing a Rhino recently and have him at level 33. In my opinion it is a great class. He is a self-sufficient tank that doesn't require a mage to be present at all times. His taunt is far better than the bears because of the DpS. Plus he has Heal, Revive, and Buffs. So what if his DpS is low? You're a tank/support! I find the Rhino to be the least boring class as I am a veteran MMO player. Having played EQ, WoW, Fiesta, and SWtOR. The ability to do multiple roles gives you the ability to change your role when one role gets too boring.
