I agree with Kazey here. Your primary role is to survive. Second is threat and in that regard we have many tools to help supplement not having exp/hit on our gear. Glyph of Vigilance, Glyph of Taunt, Glyph of Devastate, and Glyph of Revenge. Also as mentioned exp/hit food and tightening up your priority rotation.
My general rule of thumb for exp/hit:
-Take what you get in the form of equips through the natural course of upgrades and try to maintain 26 expertise skill.
There is something so appealing about backhanding someone across the face with a shield.
