Is my build okay?
I plan to use her with: Aglaea, Phainon, Archer, DoT, and Saber. No HP scaling teams, so I'm not sure if it's worth building her crit stats.

This shouldn't be the case. It's a great ability that, in theory, has nearly endless things you could do with it. I remember when the game launched being amazed by how clever people were with them.
But over time, it went from a really creative tool to simply a way to buy an extra team fight. 95% of portals you see always follow the same route: Friendly spawn -> Site/payload. You have a wormhole that can connect any two parts of the map and all it's ever used for is saving 10 seconds on the walk back to site.
It could be used to help set allies up like with punisher turret or Wanda ult. It could be used to block off enemies on certain maps. It could be used to distract or confuse enemies. And, sometimes, it is used for these things. But the overwhelming majority of the time someone is portaling, they're portaling from spawn to site and they're doing it because they don't have time to walk back. An ability with infinite creative possibilities reduced to being a tool for the same situation every time.
I cannot for the life of me clear Dire SSA. So I'm wondering if it's a build issue or an execution issue.
I cut off the 4* to keep the image from being needlessly big but I have most of them.
I've seen people say that Robin's attack buff is oversaturated for Aglaea and isn't that great. Does this mean that swapping Aglaea from Atttack to speed boots and Attack to ERR rope would be worthwhile?
Is Cerydras sig a noticeable increase? I have all the other notable early investments for Phainon. (E2S1 Phai, E2S1 Cyrene, E1 Cery, E2S1 DHPT, E2 Sparkle)
Is this build decent? I use her in Aglaea and Phainon teams. Is it worth trying to better her substats? Does she contribute much damage on those two teams? Are these the right relic sets for her?
I'm considering grabbing Cyrene when she comes up tomorrow. My Agy feels like she's aging but I want to use her as long as possible.
My current team is E2S1 Aglaea, E1S1 Sunday, E1S1 Robin, E2S1 DHPT. How much of an increase would Cyrene be over Robin here?
I don't really know a ton about how the team works so any advice is appreciated.
