Revelations from Patch 4.56

About the MSQ

I am honestly not sure how they will ever get the power scaling right. On one hand we do defeat old Zenos who was powered up by Shinryue and afterwards we are also able to defeat Omega and Prime Middy. Yet somehow we are now leaving our world and friends behind to travel to the first to get the scions back because we suddenly need them to defeat Elidizenos?

Anyway the only one we probably need is Urianger since he likes to make some strange plot devices...

Regarding "power levels"

It's nowhere near as simple as you make out.
First, Zenos was a man with a pseudo-Echo, so maybe comparable to us, and he had the power of a primal, Shinryu. But the WoL is experienced in defeating primals, that's exactly what we do.
Elidizenos is not the same. he's an Ascian, and he has Zenos's body. Defeating a Ascian is much harder than defeating a Primal, it's taken very specific circumstances, and immence amounts of aether, to kill an Ascian, and this is apparently the top Ascian, stronger than all of the others.

Then we account for the fact that we didn't defeat Zenos one-on-one the first time, it was a group effort.
Then we add in the fact that we're currently weakened by the fact that we're periodically being called to another plain of existence.

An addendum

It's debatable if we even technically beat ElidiZenos. Normally if you kill the vessel(even if the vessel's a corpse, like we saw in the SMN 50-60 quests) the Ascian is forced out and needs to either retreat to the emptiness between worlds or find a new vessel. Instead, we killed Zenos's body and Elidibus just willed it back up. Even if the WoL didn't seem tired after one round, what about after the second? third? It'd boil down to a test of endurance, and we don't even know if it would be possible to force Elidibus out given infinite stamina and time. Even if we did, the Garleans could just clone a new Zenos for him.

We'd need to deliver a killing blow against Elidibus then and there, and we don't have white auracite, a borderline infinite wellspring of aether, or the resources to even start trying to get them.

He has Zenos body without the primal thus the body itself should be weaker. Elidibus is also an emissary so we dont really know if he is that powerful or not but we also dont know if they keep most of their power if they take over a host. He did use some Ascian attack but I am not sure if that makes him more powerful.

We also defeated Prime Middy and Omega, both are not primals. Zenos being a group effort depends on if you see the gameplay mechanic on having a group of strangers with you as canon or not. Honestly why would the old Zenos even be happy to be our enemy if we just defeated him with 7 other people? That does not sound great at all.

In the end on one hand we got weaker through the calling and seemingly Elidzenos cheated death. So why would we need the other scions? We would only need something to keep him from getting back up (maybe something to throw him out of that body) and we should have no problem. Yet Tataru makes it sound like we would not even be able to do that alone.

It just feels like a very bad reason to leave the world behind and to go to the shard.

On "needing" our friends:

I'm pretty sure that's meant non-literally. Tataru's simply scared of us going in alone without backup, and the Scions are the best backup possible when facing an Ascian. The power scaling seems clear enough: we have the strength to overcome Elidizenos, but we need a new weapon to finish the job since we don't have access to Tupsimati or a dragon's eye, and especially because Elidibus seems to have extra weirdness going on. Giving us the right tools is basically what the Scions have always done, and that's why we need them (and also because they're our friends, of course).
