How it always works. Some times you win, some times you lose.
I had meh luck with the last two banners I pulled on(2nd week FFIX event) and this banner. I managed to score a Garland and Zid, but that was after wasting all my tickets and daily pulls. So 20+pulls and this banner, I so far got a Leanna in 11. Not even a decent off banner one.
For for the initial WoL banner. I managed to get, WoL, Leanna, Tellah, Cecil, Kefka(#2), and Chizzy-Chan in 15 pulls.
But that has also been the only banner I had a good string of pulls on. Every other one, has been mostly the same with 1 maybe 2 good pulls in 20 or so.
