Guild Wars 2

My question is can I change to another profession during the beta test? or am I stuck with the one I make?

I don’t see why rerolls won’t be possible. There’s a beta character slot, if you want to try out a variety of classes that can only benefit the test. I’m probably going to start with a mesmer, and I’m sure I’ll try out a few other classes in that slot if I have the time.

You’re creating a character purely for playing the stress test, you are not using an existing character.

I have a similar question — is the second session a repeat of the first? Ie do we start all over again if we can do both sessions? Or do we keep the alt we made in the first one?
