I think Colopl is trying to solve that powercreep issue, but people just don't know what they want. Powercreep reached climax with the release of Setsuna and Towa. These 2 girls had everything, tanky, powerfull, self heal, status guard. Then for mage upgrade they released Luca and Rain. Luca is pure support mage, she heals team, buff it, and can even revive teammates who died!! Rain is pure raw power, deals 1.5+ million damage in a single blow, but is squishy and can only heal himself when low hp with his motif. This clearly shows Colopl is trying to set again the unit roles in multi: dps needs a healer in the team. And then I read the jp players complaining about how Luca doesn't deal enough damage, and how Rain can't self sustain.. Today a new limited Christmas eve gacha was just released with the weapons. Jp players already complaining the units are not that good and not worth pulling for. It seems like they want the game to be powercreeped, and then they complain about powercreep lol. On a sidenote, they release very strong shinkis with Tetra at rank 1 atm. If you've been playing for quite some time and have some old jackpot/limited unit, you can manage well even without the latest unit from now on imo. To conclude, the free unit campaign gave me New Year Charlotte. I'm very happy about it!!
