Mhaultrarumble Gacha system petition soon to come!!!

My next petition will be on the Mha Ultra Rumble gacha system is the improvements that it needs and the benefits of a better gacha system 

Multiple people have been whining about this  issue with the gacha system or pitty system

My hero Ultra Rumble Gacha System is kinda bad

MHA Ultra Rumble Pitty System?

Mhur's roll system is not good
