If it is at all possible to restrict a character slot to a certain server, it would be very useful to have one spare slot dedicated to testing content on Blight.
I'm sure I'm not the only one who finds themselves constantly out of character slots just playing normally without having to think about the fact that going to test on Blight is no longer free. I've just reached a point now where it is no longer easy to free up a slot to do so, which means that, in the foreseeable future, I won't be able to assist in testing.
Having that one slot would enable me, and possibly a number of others in similar situations, to participate in testing on the Blight server.
