With the single target ranged taunt being reality, I've began giving some thought to this possibility.
Move Avenger's Shield to 11, change it to Avenger's Throw and take away the shield requirement. Tweak the damage.
It used to be one of the few ways a protdin could hope to range pull, but now that point is moot.
In terms of instant threat or AoE threat, HoR and ShoR and scaling judgements makes a 30s CD low-med damage instant redundant. That and threat being largely phased out to begin with.
While it is not a true gap closer(ret)/widener(holy) or snare, it can marginally do the job without getting us flamed. The spell is already there and requires little "programming (effort) and testing (care)" to work it in.
Prot itself could do better with a 41 that has some other useful effect, possibly some anti-caster ability (ie interrupt) or another "o shit button" (redundant IMO, but some prots have suggested a desire for one).
