Libram of Resurgence Thoughts

[Claudie]

Was able to pick this up in Naxx 25 the other night and was looking at your overall thoughts.

Libram of Resurgence
http://www.wowhead.com/?item=40337

I started off Wrath with Mother's Libram and upgraded to the 15 badge Mother 2.0 and have been thrilled with the added block value and threat components through slam.

I guess this could be used for pure AOE tanking but I hardly consecrate like we used to so question the value. I typically feel confident multi-target tanking with tab and hammer hitting 3 targets. Perhaps in a future zone there might be a Hyjal type encounter but right now I see this staying in my bag for awhile.

Has anyone been able to do any testing or have any opinion on this new libram.

Thanks in advance.
