If you get another scroll, after changng class, can you change back to yours?
That is a great question, there isn't any limitations that I know of yet but we will come back to you on this as soon as we have more answers on it.
Hey, I can confirm this for you. You can select your previous class. If you are a Sram then switch to a Foggernaut, you will be able to switch back to a Sram if you find that Foggernaut was not your cup of tea. When utilizing the service, the only classes that will be locked out is your current one and the Eliotrope.
So for example if you're a Sram, you cannot purchase the service and pick Sram (insensible, but I figured it should be elaborated regardless).
