Although fun to once a year make a critter/person flee the room from a roar, I don't see this roar being very useful. What would be more useful IMO, would be if it prevented an opponent from retreating or leaving the room for a duration of time. Granted, this would be more useful in PVP, but I could see it having some usefulness when training Stealth on critters.

Or better yet, just create a new roar with that functionality and leave SH how it is.
