This is insanely true. When he appeared in hologram style it was so fucking dumb. It legit gave me Mortefi vibes, when he popped up in the beginning of the story. And we know how "revelant" he ended up being.
They can still salvage this, if they somehow come up with a banger event for the 2nd part of the patch or a banger quest for him. But the vibe I get is that he is meant to be sidetracked, specially because he is running with Changli.
From my many years of experience playing Gatcha, usually when this happens to a character, it means with a 95% probability that we will never see him again. The same Calcharo has been waiting for his quest since 1.0, there is a suspicion that they forgot about his existence (And was it worth hiring the actor who voices Sephiroth for this?). Usual situation for gatcha games, some characters are given more attention, some less, and some just disappear without a trace in history.

I am especially interested to see this, since it is problematic to use her as a DPS in TOA now because of the 12-second timer on the Resonance skill, but in WW she works well as a DPS because it is not particularly critical there, only AoE is needed, and she has no problems with AoE. That is why I am now impatiently waiting for his release to see what will happen to her, I do not expect good ratings for TOA, he has huge problems there. But WW he has a chance, the only thing that confuses me is that in fact he is a single target, and in WW you want to pack as much AOE as possible into all slots, the same Yangyang is very good now because of her AoE.
