So i have been playing since thebeta and still don't understand all 3 types of currency. one is obviously "steel" and to the left of steel is what im assuming is just how many "free premium packs u have unlocked" but WTF is the star that looks like a reputation symbol i have 5 of those and have not found any way to use them. i am fairly sure i have looked thru everything and have looked online thru multiple sources to no avail . so i guess my 2 direct questions are
~1. what is the star currency used for at the top left next to steel and and the premium pack
~2, is the currency next to steel only used for premium packs?
Thank you
