Personally, I find it hard that anyone can accept this as a legitimate "solution" to handling disarm or similar maneuvers. To start with the basics, I don't buy into a combat maneuver being defined as "usable only by a specific character class once per encounter or less or someone who has spent two feats to cherry pick this same ability."
Then use practically any condition imposing power and narrate it as a disarm. Done and balance preserved.
