One of my favorite memories in WoW came in Zul’Gurub.
I remember the first time that I fought Bloodlord Mandokir, back when we were level 61 (just after BC dropped, but we went back to do ZG). The person leading the raid explained the fight and told us that Mandokir would “level up” whenever he killed someone, making him tougher.
Knowing the mechanic did not prepare me for the humor of Mandokir shouting “DING!” when he killed someone, followed by a call of “Grats!” from one of the other bosses in the instance. I just about fell out of my chair laughing.
That is still among the funniest moments I have had in the game, and something that really gave me insight into the humor of the developers. I’m looking forward to hearing that again in the new and improved ZG.
