Collector crystal cost
Should not be 50 units like it is when you start. It’s basically a trash ultimate crystal, meaning 1 stars are rampant and 2 stars are occasional. But if not all of the 2 stars are rare, you can get any of the normal ones, you could potentially buy 300 units for 5 one star hulks and a 2 Star winter soldier which just doesn’t seem right. I’d say 10-20 units is a good price but please don’t keep it above 35
