Also, for what its worth, it may be feasible that early on live this spell worked, but was later 'fixed' to only pulse once. Remember enchanters used to group a lot on live (not just solo in PoM), if you mez a mob, then cast Reoccuring Amnesia that lasts 30 seconds, it doesn't just clear YOU from the hate list, it clears the ENTIRE hate list.

Saw some mentions of the dangers back in 99 that if you cast this after you mez a mob, and mob is then engaged by tank, the tank could sporadically lose all agro and melee / wizards / healers could get destroyed easy.

Wouldn't put it past Verant to have put some 'fix' in place to shorten the pulse to please the tanking community or something like that.

Edit: OK last contribution, also saw mention that this could be a dangerous spell with 30 seconds of pulses as it clears entire hate list, and (at least back in the day) if a DoT did the last bit of damage on a mob but the hate list was clear the corpse would poof leaving no corpse (I'm assuming the DoT would do damage first before adding the member to the list?). So seems there were a lot of reasons why they wouldn't want this spell to pulse for so long.
