Change of class (is it possible to change back...)

  • Hi all

    I am in the Collector class right now. Started in a new Uni 2 weeks ago.

    I am considering buying the Discovery class, but if that doesn't give me what I want, I want to change back to Collector.

    So my question is, do I then have to also buy the Collector class, or is that one 'open' for me, to change back you. The same goes for, if I buy the General class....
