Oh damn cuz Rise of the Hutt Cartel came out a little while ago and now you can get up to 55. Honestly tho, once I hit 55, I'm taking a long break and going purely for Marvel Heroes. I've already completed each class story on the Imp side, Pubs can wait.
Nice, it is a free to play game which is cool. Right now they are running a Starter Pack where for $20 you choose the character you want to start off with and get 2 days early access. So let's say you don't get it, you are stuck with the starter characters they assign you and you'll have to unlock the characters you want to play as mainly.
