Thanks everyone for lending an opinion about this.
There really is not a question neotokyo. I was trying to refresh my memory about the fear spell to make sure I wasn't forgetting any details.
While I imagine how easy it will be to add having a mob reverse-traverse it's pathing while "feared", I am looking at a way of adding it now. I think, if all mobs wander to the same point anyway, there is a simple way to do this without relying on the idea that every mob must have pathing defined. I was going to use the safe point, since it is designated already in every zone. The mobs wouldn't necessarly move all the way to that point. They could be made to travel a given distance and turn around and come back.
I wanted to work out these details, see if the results would be acceptable (compared to how it might work on eqlive) before I spent any time coding it. It looks like it might be better to wait until every mob has a designated path.. so I will. :P I'll try to find something else to work on.
