CraftEgg has made the Rate-Up for the featured 4 Star higher!! (I don't have pictures but trust me on this one.)
Originally it was 0.500% for the featured card, and now it's 1.000% which means that you have a 1/3 chance, if you pull a 4 Star, to get the featured card.
We finally have a decent rate-up.
Have I mentioned how much I love CraftEgg???
Edit: I really don't know if it's permanent, but knowing CraftEgg, it probably is?
