Yeah, my luck's a lot like that usually. I managed to get that one SSR Dark chick when the game came out on my 5th or 6th single 300 roll, but now (After months of inactivity) I'm saving up for the 3k as well and hoping it doesn't go bad.
If it does, I'll come here too and cry my bitter tears.
Eh. I had good luck but have no idea if its good or not. I got 2 ssCharaters for all 6 colors and a few summs basicly free maybe a few 90 ens. Got into the game and started paying all donwhill since. almost all i got since has been crystal.. money gacchas were all sr max except for surpise pack.
