I personally don't get to quest too much because my friends usually either don't have the requirements for a quest that I have, or that they have already done the quest. But I do quest with my cousin when I can, because I find it much more fun when you have two heads to finish a quest. It also makes you feel better at the end, because with two people, it decreases the chance that you'll have to end up looking at a quest guide because your stuck. It would be nice for Jagex to create a "group" system where me and my friends could do quests and share drops together. Infact, this might encourage teamwork in the game and prevent so much of the flaming and... dare I say: "newbish" behaviour.
