For a new player, Lilims are decent stat-sticks. After getting 5 other MLB SSR Eidolons from events, probably yeah.Oh, then what exactly is a new player going to use for other elements? Diabolos? Or the SRs from Shop (Melusine and friends)?
Don't ignore the other Eidolons. They are there so that you can get your basics set if you started the game after those events.
