I've made at least 5 characters, and I can't seem to keep one.
The highest I've ever gotten is 24, and that's my Sith Assassin.
Every two weeks or so I have this huge craving to make a new character, play a new class, then after a few days of playing, it's just not interesting anymore.
I had this obsession with being a Sith Marauder for my VERY first character. Loved it, neared the end of Dromund Kaas, then had the want to become an Imperial Agent. So I put my Marauder on hold, played a Sniper, then got bored of her and made a Sith Assassin. I since deleted those two characters, and the only one I have left is my Sith Assassin, and my Vanguard, which I'm contemplating deleting right now.
Is this normal?
I'd really like to be able to finish a class, because I still think all these classes would be fun to play.
EDIT: Also, this is my first MMO, aside from the Free Edition of WoW.
