Whether it be working through the PvP list, the raiding list, the exploring list, the quests, or the current Hallow's End list, we're all madly scanning the new Achievements tab and ticking things off.
Personally, I've been concentrating mainly on picking up low level quests and running through the lower level instances; not only am I curious to see whether there actually *are* 3000 quests in the game currently, but doing them also lets me work towards the explorer's list, the dungeons list and reputations.
I've also been quite lucky with the Hallow's End stuff - last year I'd grabbed the Hallowed Helm because no-one wanted it back then, and a couple of days ago I managed to win the roll for a Sinister Squashling.
....Not that I would bother changing my title. I'm not one for following the crowd; I'll probably end up just sticking with "Challenger"!
