This is a toughie... A level 80 spec is pretty easy to work out, but level 70 just leaves too many tasty pastries in the bakery window untasted... I'm currently looking at this
as my spec for Heart. Heart can keep specialized into TC if Hyrion is good to keep specialized in DS.
After a raid or two when I've got a better feel for threat vs. mitigation/avoidance I may well tweak things a bit. But for now I'm keeping cautious with a bias towards survivability. No Shockwave or Warbringer are a little sad, but its only for a month.
Threat gen is less of a cycle now and more of a prioritization as follows:
1. S&B Shield Slam when up
3. Shield Slam
Anyone with a warrior tank not yet in late T5 gear will want to watch their defence to make sure that it has not dropped below 490 due to changes in our itemization. Prot War DPS got a big boost with 3.0 and is a worthwhile contribution to our raids.
