Hey everyone!

Coming back from a long break and would love some tips on progression/getting caught up. Going to be a long post so thanks in advance for anyone that's reading. Rank 99 water main with 2 star rudra, 47katk on main (which I think is kinda low?).

Soul: Herc. Still about 350 HSP from Shingen.
Water Himes: Vohu, Aphrodite, Ryu-Oh, Snow Angel, Shiva. Used a mtix on Shiva so going to awaken her asap.
Eidolons: Just the best beatsticks I can find, each around 2k atk except Tiamat at 2.5k. Is my understanding that with the release of Leviathan (and hopefully getting her eventually), I should keep an eye out for water eidolons and max them out even if they don't have the highest stat?
Weapon: 3 star herc axe, FLB rahab knife maxed (2686atk, assault+++, defender+), 3 star ssr hammer from one of the events (2286atk, assault++, ascension+), and 7 raid SR's. All skill levels are completely maxed, which is why I'm feeling a bit lost with progression. Do I just need to wait for water event SSR weapons as they come?

For my secondary wind team, I have Gaia AW and Hastur. Weapon grid is also lacking with a couple UE SSR's and the rest SR's. For all other teams, I have 1-2 SSR himes, but just slapped on off-element beat sticks for weapons (like the FLB rahab knife). Is it worth getting all the raid SR's and maxing out the skill level for my other elements? Or is that not really worth my time?

My next question is with accessories. I don't have the 4th and 5th slot unlocked, so I think that's definitely something I need to work (ragnarok raids I think?). Do I want to eventually go for the Tiara set bonus? Are there any accessories worth getting the the Accessory Point shop?

Raids - The guardian raids are new for me and it seems like they have treasure drops that let us exchange them for weapons/guardian eidolon at shop. Are any of the SSR weapons or the eidolon worth it? Or in general, what should I be spending these treasures on?

[Edit] I think in general, I'm just looking for ways to progress, doesn't even have to be with my main team. I know this game is a marathon so it'd be good to know what the long-term goals are
