Something you worked really hard to get?
For this I’m going to say Loremaster title, I’ve done it twice and for that first one I only used addon to find missing quests when I was missing only 1-3 from Eastern Kingdoms and Kalimdor. Also did it second time because I changed my main to my druid and I wanted to have same title ;P Also before helping from Blizz (since they made it a lot easier now when all the zones have their own quest count.) Yes it’s probably not the biggest achievement or the most difficult one in this game, but it means a lot to me and I know how hard I worked for it 🙂
P.S. Sorry not posting this yesterday, had terrible headache.. Stupid thunderstorms..
