Spells: Pacify duration incorrect for timeline

[Ropethunder]

Does anyone have any anecdotal evidence as it pertains to resists in the lull line pre and post expansions (Kunark/Velious).

I am curious to know how people, who had high level enchanters, recall how viable lull was for splitting level 50+ mobs in classic era and expansions, or if that was simply no longer viable at that point.

Please note that this question has nothing to do with partial resists or crit resists as it pertains to aggro, but rather how reliable the spell was as a high level enchanter targeting these high level mobs in pre-Luclin.
