The first toon I ever created was Ranger, which I played for around six hours. My first toon that I played for any considerable time was Warrior - I levelled it to 20 In between I had played Necromancer and Monk.
^^In that order, I switch between Necromancer and Elementalist earlier in the game, so they both have almost the same experience points around the time of eotn, play less of the rest of my characters to concentrate on the Elementalists, stop for a few months, now I am back to switching between characters depending on what was being "shouted" in alliance chat and what special weekend is being offered.
Necromancer was my first character. I never play it anymore due to the ridiculous name I gave him, but I still keep him to get the new set of mini's not too terribly long before they come out.
Started on a Warrior. Still have him and gets most of the hours and if any title farming thats who i do it on. I currently hav a PvE Warrior, Elementalist, Assasin, and Monk. and Pvp Warrior, Assasin, Elementalist, and Ranger

You can change his name now. yes, I know it's bascially 10$ but it might be worth it considering that it appears you spent a lot of time on him. Just a suggestion.
Mesmer. Then I tried Ritualist. Then Monk, then Paragon (recently), then Assassin (now).
I tried Necro and Ele after Mesmer too, but never liked them enough or even played them long enough to be considered in the top list.
Ritualist and Paragon are the most fun ones I've done. I would have never guessed Ritualist, but Paragon I knew I'd like, but I just didn't start with it since they aren't very flexible. Paragon was very similar to style I played in my last game.
