Maybe try to collect their rings to create captain planet lol idk and they should be giftable after hunt is nearly over. I think avas should be maybe Captain Planet and Maybe the wind girl and premium avas should be gaya and fire dude idk names its been too long since ive seen that show.
I'm sure ATA will take this under consideration and appreciate you helping them find something else to rip off. Their devs can't be bothered with thinking up stuff of their own
