Hi, Could be great after the Hand of kane rank to have new rank to have higher crates (mostly power one) because no evolution so no one (i'm 99% sure) continue to buy crates ...
Interesting idea. Additional revenue keeps the game alive so that is good, need to think about balance. Initial thought is not a big deal because of the time it takes you to get to that rank. The days where this sort of thing might affect balance on a server seem early where this would not be germane.
