Back in terms of the discussion...
Yes UF mobs hit quite hard, but it's more than doable. Also, please take into consideration nearly half or more of the mobs in this expansion can be stunned. While they do hit hard, our stuns make us the best choice for UF tanks possible
Having recently broken into Volska's hut (did all of tier 3 progression trio...me, monk, rogue) I can handle mobs there quite easily with stuns. I may have full tower gear, but I am even able to heal myself on yellow con mobs and live (it's hectic, but works). It's a matter of using twincast heals wisely, and overall being a smart tank. I love the expansion so far, and think the devs have done an amazing job at actually providing a challenge for the group game. Can't wait to see the raids (trying fippy tonight for the first time).
