Been doing the Starbits runs to 100,000 and then buying a 10 pack to get an additional two bonus packs. Bonus packs are always welcome and 4 out of 6 times, they have come with at least an Epic card in the set. 1 out of 6 had a legendary.
With that being said, why would buying individual packs be better than getting a bonus? Well, more for the excitement and entertainment value of playing the game. Saving up till the 100,000 point mark is pretty long.
It takes about a month on average and that's if I play regularly and get those missions in. Waiting for a month to open some packs feels like a really long time. So is delayed gratification worth it in this case or is the regular dopamine hit more important? I'm still thinking about it.
