this may not be the answer you're truly looking for, but if you bring a mnk or a war to the fight instead of bst, you should be able to tank any of the three. from when i last checked, the immunities to dmg doesnt apply to countered dmg. so w/ either retaliation or counterstance, you should be able to bypass the problem of which NM you end up having to kill. if you cant do anything about that job, the only thing i suggest is perhaps bst/mnk counterstand and hope for the best.

I might agree with this, except countered/retaliated attacks do not produce hate. The enemy would not face you for you to continue countering, once the RDM performs any action on you.
Of course you could try Provoke + Warcry etc...
