Blitz cards: rare, uncommon, legendary

Games Halo Wars Series

Does anybody know how likely it is to get either of the different card types. I assume the order is as follows (most likely cards first):

  • common
  • uncommon
  • rare
  • legendary

Someone on here who has opened many packs and kept stats how often those different cards occur?

So I opened about 15 Blitz Packs… here is the distribution I received:

common - 36%
uncommon - 44%
rare - 18%
Legendary - 2%

So it seems that uncommon cards are mor common than common cards. Not sure if this is a bug, I got really lucky or I don’t know. It doesn’t really make sense.
