I'm personally not too fond of water because of it's debuff-reliant playstyle that doesn't really change till much later, so I would recommend you run the Kirin account.
Thunder currently has it a bit easier at the lower level rarities: Perun Cyclops and King are all pretty high tier in their own right. Drop in an Astraea too if you so desire to run debuff content for now.
//Gryla will be soon, she is thunder sr heal.
SSRs wise, himes to absolutely look out for: Marduk, Baal U, Brahma, Athena, Raiko. These are what I'd label as the absolute first thing you should miracle ticket for. Notable mentions, aka the less important ones: Mammon (I'm sensing pitchforks), Thor (if you choose paraslave).
As for water, no top tier R himes really stand out to me, except maybe yuri meatshield Kushinada. You do have quite a selection of SRs though, most notably Belphegor, Triton and Venus.
//Dagon is nice water R, only Zephyrus and Konohana are better.
Water SSRs wise, absolute picks: Snow Raphael, Asherah. Maybe Ryu-Oh. Less important picks: Cthulhu*, Shiva*, Poseidon*, Aphro or Nike U.
Those that I marked with a * means they don't stay in that tier forever. All 3 will get an AW (Poseidon is the earliest, in 3.5 months?) that will probably change their placing in terms of priority. Shiva and Cthulhu AWs are really late though, so don't count on these picks unless you're doing long term investment gymnastics.
//Posseydon is garbage even after AW, Shiva aw will be top tier damage dealer,not so suicidial as Lakshmi, Ctulhu gets almost nothing after AW - just hearth replaced with other hearth-like effect, stackable with hearths and more +self burst on skill 1 if orb is consumed. No cd reduction, no damage increase (just minor stat boost), so she will be almost the same. I disagree with water Raph as top tier hime - she is good support, but can be easy replaced. My miracle order for water is Vohu (when aviable) then Ruy-oh/Asherath. Asherath is so good because water has not so much buffs, so she is hard to replace.
I disagree, than water's damage is lower then other's.. maybe right now it is so, because no Vohu/Lakshmi/Shiva aw yet, but it will be changed soon.
