If I want to get the Resourceful achievement, can I delete a class I already got to 80 and start a new class? Or will I need to buy 3 more character spots. I ask because I have a character at 80 I know I will never play again, and there is one class I have to level to 80 I know I won't play beyond 80. If I can delete the 80, level the second class to 80, delete it, then play the final class I would.
Thanks
