What's the point with that quite lackluster story in Endwalker?

Yeh. Though the timeline of events we were given was fuzzy, it sounds like she let them summon Zodiark and then started lobbying her point. Zodiark was necessary for her plan too, after all. I always really did hate her logic of why she never told the Convocation what was up. She knew as much as Hermes what was happening. Hermes only knew more about Dynamis because no one else really cared. If she had gone up to the Convocation and told them what was up, perhaps they could have used that information to actually find a solution to the problem rather than just the stop gap they came up with. If they put their best minds on studying Dynamis, they prolly could have made quite a bit of progress.

Sadly we will never know.

I'm going to play devils advocate for a bit on this. (Note I still disagree with her) Perhaps her thoughts were that she needed Zodiark to be constructed without her interference because if she got involved it could influence the end result and make it less helpful. The WoL told her how long Zodiark had been around so that's a timeline of Zodiark working and working in pieces, but the WoL has no idea how Zodiark is actually constructed. By getting involved and changing the plan then her thoughts could be "maybe I could make things better, but I know this idea worked so I shouldn't risk that plan not working".

Still convoluted and idk if I'm even doing that logic train justice.
