I must say, I rerolled for exusai and got ifrit in my first ten pulls. Then got a saria in the recruiting in the first week and thought to myself that this was going to be an awesome game for top operators for me. Queue one month later, and 80 pulls later on the silverash banner and I only managed a dupe ifrit.
Not to worried since I was collecting yellow certs for silverash. Yesterday however, I managed another top operator tag and rolled without any modifiers and got siege (one of my most wanted). Right after that, I got a nuker tag for fire watch. Thought, what the hell, my luck is pretty good today and rolled 10x on eyjf ifrit banner and pulled eyjf. I went up 60% in 6 stars.
So keep the faith guys, luck can flip.
