Love the game but

I love this game and how it plays, however Ive completed the entire story mode got all the soul orbs and got all 300 possible from co-op and Ive only managed to get two 5 stars and they were both Ulquiora, Please change the pull rates for 5 stars or at least lower the price for summons I shouldnt have to spend 200$ on a free to play game and not get a 5 star
