This week, I finally learned to find the exit of a dungeon my alts run somewhat regularly. Before, I'd always hope someone else would be running out so I could follow them, or I'd click out and have to travel back to the area to continue questing nearby. Don't ask me which instance I'm talking about; I refuse to implicate myself that specifically. Let's just say I'm outta there.
Maybe you finally got the hang of dodging the AoE during an encounter that's been giving you fits, or perhaps you checked off that piece of gear you've been lusting over for weeks. How did you up your game this week?
