Strictly speaking, this does not mean they will overhaul Ret. Just their talent tree. For all we know they might just move the nodes around.
For example, if Blizzard seperated some of the defensive talents from being choice nodes and moved further up the tree, while simultaneously turning a lot of active buttons into choice nodes. And then slapped Long Arm of the Law or Pursuit of Justice in the talent tree somwhere. They will have addressed all of thier points. Except for the one about stacking modifiers. But that can be fixed by simply making a lot of those talents into passives.
The end result is basically the same spec, but with some of it’s weaknesses shored up.
