I've been playing this since day 1 and have still yet to unlock anything legendary or exotic, thus I can't level my Titan past 24. How unbelievably rare is it for this stuff to happen? I've gotten a total of 2 legendary engrams (both from the postmaster): one gave me legendary armor for a class I don't use (Hunter) and the other gave me a legendary Titan mark, which I already have 2 of. Do I need to play for 24 hours straight or something? Do I have to just take a day or two off work and play non stop so I can afford to maybe buy something? Help!!
