MMO-Champion keeps giving us updates on the World of Warcraft: Wrath of the Lich King-beta and in the latest patch a whole new bunch of titles were added to the game. It's nice to see World of Warcraft joining the title-train for real, even though they are a few years behind everyone else...
The new titles include exclusive titles for the people who reach level 80 first on their server, or manage to cap their proffession before anyone else. There's also the wonderful title "Salty" for people who complete all the fishing achievements. Personally I would love to get the "doctor"-title for my gnome rogue ("no heals for the dps, use bandages!") but there's no way I will spend much energy (no rogue-pun intended) trying to get First Aid to 450 before anyone else.
Check out the complete list here, you'll have to do some scrolling to reach the titles though.
