Declining quests has become a way of life. Here are a few reasons to help you justify it:
You have too many quests, your inbox is filled with notifications, and you're starting to feel like a quest-giver.
Your guild is judging you for not having any progress, and you're starting to feel like an outcast.
You've been playing for 12 hours straight, and you need a break from the constant stream of "You are 2 levels closer!"
