Apply the last line that I mention. The only content I see you struggling really hard with is wind, which kinda sucks because (ahem personal opinion) I consider wind one of the toughest elements to deal with without elemental advantage. Since you already have a OMEGALUL chain burst wind meta team, an ok(...?) light team, and a workable(?) with thunder team, however, the value of having a single team to handle everything decreases... kinda.
Don't look at content that shoots too far into the future however, Vohu Manah won't be till 5th miracle most likely, and we don't even know what Shiva AW does yet, and it's a dang year anyway.
Statistically, going for Asherah is the better option since you need only a single hime for water, as compared to... a couple of viable ones for dark till next miracle ticket (Pluto, Cherno, Berith, Samael(? really depends on when the 4th miracle ticket is out)). Water gets really cucked 4th miracle season it appears...
It'll be a really tough choice, but seeing that you're probably a wind main... having your water team properly set up seems to be the wiser choice in the short run. That's really all the input I have that's worth really, I still stand by saying that your water team is gated by one, and only one single hime, and yada yada yada, sorry I can't put anything more
