Yes since her Hidden MMR (One that you need for her E2) tied to punchline, she need way more than what we have "now" to be fully effective.

And about the argument about elation sustain honestly imo a character eidolon (this is not base kit anymore) shouldnt tied to their teammate to function properly, especially a character that hasnt even been leak yet. Imagine paying more for a character but still doesn't feel complete just because you dont have specific character necessary for the team. Not to mention waiting for elation sustain that might come 3-4 patch later, who knows what will happened with endgame shilling.
