Yeah. It's still better than a useless dupe I guess.

They don't have to make all old girls OP but at least, raise them to today standards. Somes are still good like Dendro or Cattleya, some have very niche abilities combo and can find a purpose but most of them are just trash combared to recent okay girls.
Sure the 5 release girls are free but they could be buffed. It's not like having one full team of given 6* is enough to beat endgame content. 5 free 6* already allow any new player to beat all the basic content easily.
In the past, getting a gold pot was a thing and rainbow pot was holy grail. Now rainbow pot is the standard and you pray for something good out of it. That's sad. Or maybe we are just old players too used to the thrill of the rainbow.
