Yes its worth it and should be in all frost builds. The talent is budgeted perfectly. It gives the same damage reduction point for point that BB does now without having to proc it.

The build itself has a few "flavor" points that you can place however you see fit. I will most likely place them in BA to fill that out.
A few key points about frost builds:
1. OB is your main filler spell (and may be the main attack with Ulduar weapons)
2. Point for Point, 2H spel is better than BA. This is due to the fact that OB, RS, and FS will comprise most of your TPS.
3. 4/5 KM is plenty
4. Points in Runic Mastery are not really all that needed from a tanking point of view. If you are used to running with BoSanc your in for a rude awakening with RP starvation. If you have been running with out it, you understand what im saying. Also, FS is a very good ability that it should be used whenever you get over 60 RP.
What I would be interested in know is if keeping PS up is worth it. With the glyphed HB, is it even worth using the new PS? I can see the rotation looking something like this:
HB OB BS BS FS.... OB HB OB FS
I cast the spells that make the people fall over.
