With a 30% reduction in rage cost, however, T&C becomes 20% MORE rage efficient then FR, assuming no overhealing, and assuming the formulas remain the same going into WoD. Meaning, of course, outside of fights where portions of the TC absorb is wasted, TC will ALWAYS be a better choice then FR. (More mitigation+damage component)
Of course, it not quite as number-y as previous free TC, but with a free TC, it was basically a button you could push whenever it lights up, no thought to it.
The main problem with the most recent changes though, is the greatly reduced rage generation, like what Arielle has said. Since SD maintanence requires 6.6 RPS generation, 7.8 RPS means that you can only use 1 maul per 20 seconds, or 1 full rage FR per 60 seconds. And, of course, with the rage gen changes, the stat investment to get more RPS isn't worth it. (2k haste or crit for 1 extra RPS, as Arielle has mathed out, is equivalent to 20% extra Multistrike, or a good HP boost).
I would revert all the RPS changes, and just make FR/TC mitigate less damage.
