Lightning strike casted via wrath proc (wrath makes your next cast do 20% more damage and be instant) is a dps loss over just casting force lightning. How sad is it that a casted ability made instant cast with 20% more damage still is worse than madness's filler move.
Exactly right. These powers just don't make sense. If they are intended to be our filler move, then make it insta-cast and make Presence of Mind (and the Madness equivalent) and other boosts to it increase its damage significantly.
