Will Fury Execute OH function like RB OH, Storm Bolt OH or Whirlwind OH? Also, did any of the following mechanics change?
In Warlords, as of next build...
Execute, Raging Blow, and Storm Bolt will work like this: Perform the Mainhand hit roll. If successful, also fire the Offhand attack, which always hits. (Same as now for RB, different for SB, new for Ex)
EDIT: Slight technicality here, if you're looking at the spell IDs involved in the logs. RB's root spell is just a cover spell that contains separate MH and OH spells. The root spell can miss, the MH/OH spells cannot.
For SB/Ex, the root spell is the MH damage, which can miss. If it hits, it fires the OH spell, which cannot miss.
