Heh... there's an old alliance quest in WoW, way back before Cata, in which you had to escort Corporal Keeshan out of captivity from the Blackrock Orcs in a cave in Redridge Mountains. Originally this was quite a difficult quest, as the orcs in that cave were both very numerous and very strong, and Keeshan himself, who was sitting in the back of the cave, was quite weak and fragile. Often times you needed to either have help from other players, or just out level it, and you always had to clear ahead of Keeshan's path, because he liked to attack anything vaguely nearby and died quickly.
Sometime later, Blizzard put out a patch that, among many other things, made this quest much easier. The orcs were still just as numerous and difficult as ever, however... Keeshan himself was upgraded into an Elite, with a lot of health, a lot of damage, and he taunted everything that he hit. Now you had to go out of your way to fail this quest. Keeshan was made so strong that you could literally just walk behind him and let him deal with everything, without helping him in the slightest. It was still an escort quest, just now it was Keeshan escorting you.
Funnily enough, when Cataclysm revamped all of the old zones, Keeshan was then turned into essentially Warcraft's version of Rambo, and had one of the best questlines in the game, doing everything from stealthily scouting out an Orc camp and placing "Seaforium" charges around, to driving a siege engine to kill an entire orc army.
