The current Achievement system is extensive, and growing. While many seem to exist just to give you a small pat on the back, others push you into new content, silly stunts, and wacky doings.
Which achievement gives you the most pride? There's a lively discussion on the forums about the matter, and we'd like to continue it here.
It seems like a simple question, but when I began pondering my answer, I wasn't sure what to choose. I'm proud that I have completed every meta achievement leading up to What a Long Strange Trip it's Been, so far this year. I'm not sure if that should count yet, considering there are still plenty of chances to fumble the whole thing.
I believe that I will settle on Twilight Assist. Sarth with a drake or more up is definitely the hardest content currently in the game. Although we haven't managed two or three, I belong to a small, tight-knit raiding guild that started from the ground up. None of our players are recruited from elite guilds, and we don't have 25-man gear. Getting this achievement was an awesome feeling.
So I ask again, of which achievement are you most proud, and why is that the case? Was it the most fun or challenging? Was it because of a reward or title?
