If you dump half(dual spec) or 2/5ths into dex, your hit percent and damage will go up, allowing you to gain more aggro.

Things I'd say: 5 taunt isn't really that useful at your level, it would be more productive to put those into beckon(unlocked at level 22), stomp, rage, and hell scream.

Rage has a hidden +60 damage buff at level 6, which is amazing at lower levels.

Just a little picture of beckon at level 6, it'll pull everything towards you, and then once you stomp into the wall/ use HS to keep them stunned, your team will have a much easier time with their AOE spells.
