It's not marketing if the rewards are free 
I made the quests for fun all by myself and to add mystery to the game, if it's announced with clues and all this other decoration every server has always had then it would not be true exploration now would it? |
The problem is with them quest it doesn't give inclin on where to go where to start etc should atleast have in news Bob the NPC has a quest(they may have to go find bob-but least they know where to start.)
