Going to be really tough to keep things going in block stance if you have top tier dps gunning against you. Just use threat stance. I also try to get my crit up to a decent level and use the Armor of the Erebor Defender 2 piece bonus for Shield-Blow and then the 4 piece Barad Guldur armor for its Threat Over Time bonus. Also don't worry too much about your axe and DPS. Your main taunts are litany of defiance, shield taunt, vexing blow, shield-blow (since it's a fast hit). I even toss in fray the edge since it's another ToT.

Don't forget to work in Whirling Retaliation to leech some threat from people, too!
In the worst cases you might need to use Engage and Challenge the Darkness to copy the threat and put yourself out in front for a bit. Just make sure that if you're going to do that you have a litany or shield taunt ready to stack on top of it quickly.
