HBR has a 300 gem per roll gacha, no weapon banner, 3% SS pull rate, a 150 pull guarantee, also a free SS dupe system, AND they give out free guaranteed SS tickets several times a month.
Meanwhile Stella Sora has a 300 gem per roll gacha, a 2% rate 5 star pull rate, a weapon banner also with a 2% pull rate, and a 160 guarantee.
Clearly these games have very similar gacha systems except one is giga kikemaxxed and one isn't, yet both are ran by yostar? how'd that happen?
