I found my Fallen Hero did much better at tanking at that lvl. Although using UA at lvl 30 he seemed to be better than before with training pet buff. If you don't have Fallen Hero I personally would consider respec-ing. Fallen Hero is that much better imo. I still use him at 34 in certain situations. But it just all depends on what you do mainly. He solos lots better then UA. Also if you have a tank in a group that can't seem to hold arrgo off of you, FH can jump in there and sometimes pull them off of you and save your butt. At that lvl you can fire off petrify and sick FH on them, when petrify wears off, FH will have them, instead of them having you. I know he has saved me lots of times fighting mobs under lvl 32. Hope this helps.
