When the app launched I did about 6 pulls in the span of a couple of weeks and ended with a few 5 stars. Since the updates from 1.0.XX I have pulled nothing but 3 stars 5 out of 5 kind of shit bundles, or a couple of 4 stars from the starting characters (not even the new ones for fucks sake) for an additional 6 to 8 pulls. Because I am no whale and I get my thrill out of every once in a while getting something worthwhile, I have deleted the app. This game has the worst Gacha I have ever experienced post updates.
I can only handle so much heartache from RNGsus, and even Love Live is better than this shit.
