i am playing a brawler on eq2 and got a sk and a monk on eq1. in eq1 if u FD and stand back up in the mobs aggro range it attacks again and on several occations recently i noticed that if i FD and a mob wonders off to the other side of the zone and i stand up it comes all the way back to beat the crap outta me.
BUT....
in eq2 the designers wanted to make it so people could not train mobs on other players so if u aggro something and do a FD the mob will ignore all players til it gets back to its original place or area(unless u are grouped). now as this applies to the FD issue....
once you FD u are erased from the hate list and if you immediately stand back up the mob ignores you and moves back to its area.
now there may be exceptions to this and i could be wrong, but so far all the testing poking and provoking i have done has confirmed this.
hope this post helps
