As one of the few Wizards with IC in classic, I took whatever I wanted from any dungeon. It was all about damage dealt, Guides/GMs started to care later on closer to Kunark release when "play nice" rules were implemented, but I was able to circumvent that by telling the group that I was willing to share with them and we'd alternate: one kill for me, one kill for their group, one kill for me.... People lost their damn minds (obviously) and would just try to contest it. Loot was awarded to the highest damage dealt by a PLAYER, not a group... so KS'ing a wizard with IC required a cleverly timed mem blur and smart Enchanters weren't very common in classic.
