Yes, ..... I agree. I have over 500 total of 4* & 5*.... useless.
We grind for awakening materials and get tons of irrelevant stuff!
I feel these days, I'm hanging on by a thread.
Shame that the game doesn't allow trading between players - I'm doing my damndest to get 8 more 5* colorless so I can fully awaken. Meanwhile, I have tons of random stuff I don't really need...
