10 Video Games That Punished "Cheesing"
4. The Cleaner - World Of Warcraft
The Cleaner is an especially unusual NPC in WoW, in that they basically exist to make sure you don't get help in specific quests.
Stave of the Ancients - a quest that now is only properly accessible in WoW Classic - utilised this to the best of its abilities. The idea was that you would face off against several powerful enemies alone, and in order to dissuade players from ignoring the fact they were supposed to fight this battle alone, The Cleaner was born.
If anyone but you hits your target, the demon arrives to "clean up" - which, in this context, means to murder you in cold blood and then go away.
The reason this became such a problem for many, as you might already guess, is that several classes in the game rely on damage dealt from outside of your weapon, such as the hunters and their pets.
Which created wonderful chaos, as many wondered why they were being straight up murdered for doing as they were told.
