As a f2p, I would focus more on this year's expansion of legendaries since you will be able to use them for much longer if you're thinking long term(I'm sure you know this already). Can't go wrong with Edwin Vancleef if you want to play miracle rogue. Even though Jaraxxus is so cool, the new warlock death knight seems like a much better option. Good luck with your decisions!
