I'm letting you know what hapened to me. I had 60/100 edo Yagura frags, so getting him twice would allow me to 4-star him. I spent 210 seals, got him.

Good start I felt. Pulled more, got edo Fu. Ok, it's still 50/50 chance so no big deal. More seals used, another Fu. At this point I started to get worried. Kept pulling, total seals used: 830. Got edo Fu 3 times in a row. 12,5% chance of that happening and it happened to me. Now out of seals and stuck at 80/100 frags,

I'm just one of many who feel Time-limited treasures should work like other treasures. If you get 1 super rare, next one shoudn't be the same. Our current version just makes us waste seal scrolls. Or Oasis could have just kept time-limited treasures with different super rares, so we'd know what we pull for. Seeing Time-limited 3 we know it was possible.
