So you've paid for like 1500 medals. I've had 2 rainbow dupes and gotten like every free d medal since they're been added and I'm only slightly over 500 total rainbow medals. It's been about a year since they added them and so far there's no sign of them coming at an increased rate. Maybe it will get better but it's still just a lazy system that just looks like a money grab right now. You can buy 22k total team power for 2k rainbow medals. The bonuses aren't even unique or catered to girls kits. You would think if they're adding some new system it wouldn't just be the 3000/1000/400 amp bonus, but it is.
