One thing I'm sure all of you realize, but I'll go ahead and mention anyway.

Some Weapon Skills do not go to AoE, even under Steadfast. So if there's a chance I'm going to accidentally AoE, I'll usually switch to WSs that don't AoE under Steadfast. That means no Skull Sunder or Brutal Swing, but I can still use Maim and Trunksplitter.
