The recent new characters have been too overpowered and it makes the old character useless ,they did make the old characters to have the same skill but you need to collect a material that is rare,and what is it with the gacha rates.in the past its not that hard to get a new character with just a few roll but now, i need to roll 5 time to get a guaranteed 4 star? And well i always get the old characters which is not what i wanted and to roll 5 times i need to farm a lot, this turned to be a P2W
