We are currently 2/7 Heroic Firelands.
The raid leader asked everyone to consider any survivability talents as we are working on the heroic encounters.
I know the Disc tree has two, Inner Sanctum which can reduce spell damage by 6% for 3 talent points and Focused Will which reduces any damage by 10% (stacking twice) after you take damage greater then 10% of your health or a non periodic crit.
Inner Sanctum can be useful in a few scenarios such as getting attacked by dogs on Shannox or perhaps when Flame Scythes are coming less then 8 seconds apart on Staghelm. I wasn't sure how long apart Ember Flare was cast in P2 of Beth'tilac or Blazing Buffet on Alysrazor. On Rags I suppose you get some benefit during the Molten Inferno from the seeds exploding and after if the Elementals happen to target you.
So basically I'm trying to decide if it is worth 2 points or if there just isn't enough benefit to justify using 2 points that could easily be used elsewhere.
Since my 2nd spec has currently been switched from Holy to Shadow I have been trying to rework my Discipline spec to be more versatile but have been having trouble deciding. It was thinking an Atonement spec with 4 points that can move around. The choices for the last 4 points would be...
2/2 Soul Warding - If I wanted the flexibility to multi-shield in emergency situations
2/2 Train of Thought - For more free casts / very situational Penance cool down reduction
2/2 Focused Will - If the survivability is worth it
2/3 Darkness - If I want to hit the 2.5 second casts -> 2.1 seconds haste plateau
Anyways any discussions on Focused Will or talent choices are welcome.
The link to my talents are below but they are kinda a mess atm as I was testing Focused Will
