I don't know if its intended or not, but taunt DRs aren't shown at the Lich King Encounter. Do you have to specially enable it for every encounter? Because taunt DR's are active regardless which mob ...
Tested it with another mob, a level 76 crocolisk did not have any taunt DR... but LK had! ;D
I'll look at how LibNameplate works, and maybe make it a separate module.
Edit: ok, so the issue is that DR is specifically designed to work with SecureUnitButtonTemplate. It would require some overhaul to have it working with nameplates (or any arbitrary frame for that matter).
Not having an issue myself with DR, but a user on wow official forums couldn't log in here to ask for some reason, kept erroring out. So I volunteered to post the link to his thread with the error/issue he's having in hope he could get a response from the author: http://us.battle.net/wow/en/forum/topic/3278808985
I own an EU account so I cannot post on US forums. Could you tell him he can register on curse.com and use the same account there ?
As for WoW base frames, this should be still working, though I did not test them recently. For the nameplates, it is completely relying on LibNameplates-1.0 by Cyprias (http://www.wowace.com/addons/libnameplate-1-0/). It is possible it got outdated a bit... I will take a look ASAP.
