FD and Green Pet argo on Green ?

[vanix]

I seem to remember sk's and necro's making me feel some type of way with the ability to FD and send in a low lvl green pet who will argo which ever of the 2000 mobs say in ntov and pull it right to the raid like with the precision that such a retarded mechanic should never do but somehow seemed very real back in 06.. so why does'nt this work on blue or green that i know of? I mean this sneak pulling exploit was something i never knew of or needed back then and yet everyones doing it and crying when its gone yet what ever happened to the pet pulling exploits? I mean its hard keeping track but im pretty sure prog server #1 mechanics dont include nerfs to this and p99 will never get there on the timeline so wtf? i require answers please
