But if the point of the game is to get high levels AND have fun,
what is the point of making a huge deal out of something that can't even pass for a "skill?"
A skill is meant to be the training part of the game.
You do dungeoneering to gain EXP in the skills you use, it's not as quick as anything else but you do it in a much more fun enviroment than just grinding away for days with nobody around you.
In doing this you gain points which can be exchanged for items that work with these skills and help you outside of the dungeoneering skill.
It was designed to boost the entertainment value and community aspect of the game, considering there are no parties in general play on Runescape this skill works well for this, it also gives good rewards if you keep at it as a side bonus.
Makes sense, doesn't it?
