I personally think the game would be a lot better if players had easier access to individual champs. I would like to see the drop rates go dramatically up. Currently the uncollected character Crystal's that can be bought for 300 units have about a 1 in 220 chance to get the 5 star versions of the featured champs. That's really low. Maybe more people would buy those more often if there was at least a 10 percent chance.
