One of the worse monetization by bandai. In-game currency is extremely limited, pity for a single character is at a whopping 300 summon and no chance to obtain that amount even if you complete the story mode. Memories or equipments are in every summoning pool so your rates for characters get diluted even further. Farming for material is tedious since the drop rate of materials are ridiculously bad. Characters you can pull is not diverse with todoroki, bakugo and deku repeating countless times.
