Ya gunbreaker was an odd choice for a tank. At the same time though I honestly understand the job and design choices the devs make for tanks. Since tanks are generally the most in need role the team makes flashy tank jobs to appeal to dps monkeys like me lol. If it wasn't for WAR I wouldn't even consider tanking, though this expansion I haven't really leveled it at all because I don't like the all out healing style its become. I miss my unga bunga WAR tank from ARR and HW.
