It could just be a coincidence but since I put the legendary card as my front man, the earnings have been higher than usual. I still don't see any reward at the top of the range but the earnings have more often than not been around 2000 Starbits. But yeah, it would need a few more completed missions before I can draw a conclusion.
Earning at this rate would mean being able to buy a 12 pack in half the time. Probably about 15 or so days depending on how many missions I'm able to complete. If the earnings drop by half, then it would take closer to a month more.
Getting an Epic card a month is pretty good in my opinion. Previously it took much longer despite buying individual packs regularly.
