The other day I was playing WoW in Sunstrider Isle with my new Warlock and one of the quests asked me to kill corrupted Treants to free the land from their evil presence..
Treants are basically anthropomorphous trees that roam around and do mainly (but not only) physical damage.
Point is, what kind of reward would you expect to get from such a creature once killed? Try and free your imagination... "A piece of tainted bark", "A corrupted branch", "A piece of Treant ligneous brain" maybe.... no, of course not, I got coins....
COINS???? what for??
then after a while i understood... One of them also dropped a glass of Milk and I realized the coins were for buying a croissant to soke into it!!
