It's forgettable because it relies upon a nebulous requirement to be both fulfilled by the player and acknowledged by the DM.
And it's rarely used once rewarded because the player knows it's rare, and thus holds off on using it until they're in a pinch - at which point they forget about it in the excitement of the moment.
The new version goes a long way towards solving both of those, being triggered by a concrete event that players are already primed to take notice of, and - as a result - showing up frequently enough that players should be more inclined to spend it relatively freely.
