Well reaching Level 40 was one of my goals, now I guess I just keep amassing Starbits to buy more cards. I do not use up much time with this game just set up what mission I am taking and let it run.
I guess it will be slow going but with time I should get to level 100, for now I am going to work to be able to buy my next 12 packs, I guess that should take at least over a month.
