Yeah, I can understand the impatience, but the chance of getting legendaries in packs is so minuscule, I wouldn't even bother as long as you can't buy a hundred each day.

With a million Starbits daily you would be able to buy 120 packs. Your chances of getting a legendary would be 0,05x120x3 = 18%
I started buying packs regularly well over that threshold and I'm still buying cards as well, to be honest ^^.
