Yeah there's no reason to use anything except minimal resources on less than a 5* when you 50 plus event girls and equip staring you in the face
I was lucky and had those daily free pulls to build a huge stockpile of girls around when I started. I got most of the event equipment from the reissues but still need to go get those girls someday. At least the ones that have a CSQ that pays some gems
EDIT
Don't forget to sell those normal gacha seeds if you need gold now. I probably have millions there if I took the time to sell all those girls.
