Game Mechanics: Pulling while Invisible

[Treats]

As is right now on P99 you can cast on a mob while someone else is casting Invisibility on you and ONLY aggro the mob you were casting on while running anywhere you please in the zone. Logged on EQMac to see if this actually worked.

Different types of spells there seem to give different results
Some will break the Invis once the spell has finished (Bolts/Lifetaps/Anything that seems to be emitting or having an effect on the player from a spell)

The above however doesn't really matter. In all of the scenarios I tried while keeping the Invisibility up it did not work. None of these mobs could See Invis.

Scenario 1:

Shaman started Invis on me
Casted spell on one mob in a pack of two
Spell lands while Invisible
Both mobs aggro disregarding the Invis that was cast on me

Scenario 2:

Aggroed one mob
Rooted mob and built aggro
Shaman Invis'd me
Ran through a pack of about 4 mobs (No aggro on them while Invis)
Root wears off original mob
Paths through the pack of mobs I ran through
Every one of them aggro'd disregarding my Invis as the original mob ran through them

I just don't see how Invis pulling through packs on Live was possible. I sure don't remember it. It would have been a huge mechanic flaw that would have been fixed ASAP.

Does anyone have any hard evidence that this was possible on Live during the Kunark/Velious Era? It certainly is not on the PoP locked server.
