While not an overall bad post... there's a few things I want to nitpick about.

While not exactly untrue, there's also the problems with loading screens. Let's face it, once you get decently powerful, you're spending like... over half of your time in freaking loading screen. At least the "Fight Again" button has taken a few loading screens away, but still, there is a point where completing big tasks are more valuable than small tasks, if only for the reason of avoiding loading screens.

Now, if only that was possible for everything, such as farming T2 Cores. Nope, gotta spend like 90% of my time in loading screens during those.

And getting those big numbers requires you to be efficient with time management.
I don't think you should be saying 3% to new players. It's 1.8% for SSR Hime and 1.2% for SSR Eidolons, the latter being basically useless for all non-whale intents and purposes.

Soooo... please use 1.8% instead?

On HBC, you should always use bold for links. Otherwise it's hard to notice that there is a link.

Also, why isn't nonsensei's guide linked?

2. 10 R + junk SSR + 2000 gems -> LV 23 SSR
3. 20 SR + Good SSR + 2000 gems -> LV 37 SSR
4. LV 37 SSR + 9 x LV 23 SSR + 1N + 37000 gems -> LV50 SSR
Is... is that smart? Does that work if you do AQ4?
Ever since AQ5 came out, the drops for AQ4 changed drastically, so I can't say that WOULDN'T work... but 23 leveled up SSRs seem like quite a lot of effort.

But I haven't bothered with item squishing Accessories ever since AQ5 guaranteed SSR drops, which is also true for AQ4 now. I prefer the 1-2-3-4 method, where you use 1 N, 2 Rs, 13 SRs (totally 3, right?) and 4 SSRs of the same element. This is easy to remember and pretty much exactly the halfway point to level 50 (so you don't waste any exp if you get a Super Success on your first try). It's also convenient for AQ5 drops while working on all elements, but if you focus on AQ4 and just one element... well, I can't comment.

... are the Jewels important?
As I said in another thread, you need ~120833 Jewels to find a top tier Hime from the gacha. Not exact maths, but just as a case of point. The point is, is that 3000 Jewels really going to do jackshit for you?

Meanwhile, how is a new player supposed to know when an Eidolon is worth it and when it isn't? Especially these days when Advent event grind required has been significantly reduced, I don't think that you should brush off the Eidolon like that.

I don't think new players are going to need T4 Crystals (aka Stars). The biggest usage of Stars was for Union Event FLBs, which required a whopping 25 each - further burdened by already having several copies of the weapons due to past events! But because good Union Event drops are basically history now (just one last final Wrath left)... well, I kinda doubt new players are going to be troubled by T4 Crystal drops.

And this is before the drop changes which make Fangs harder to get and T4 Crystal far easier to get, supposedly...

I don't really think that's going to do much. First of all, minimum wage won't get you all that far in Kamihime.

Second, even whales have to do the grind. There's very, very few offers for... say, Magnas to be bought with real life money. You would think that considering how DMM is in control of the droprates, the awful awful AWFUL droprates that we have were made in order to make people buy that shit. But no, they run a special about being able to buy a measly 20 for 30 bucks every couple of months. And you're limited to two packs! That's 40 Magnas, when you need 60 for a ONE SINGLE SSR HIME! It's absolutely insane when you think about it. Why are they choking the playerbase if they're not trying to exploit them...?

Sure whaling gets you stronger, as you get more Hime to build teams from. And P2W Eidolons in particular are extremely strong, but those will cost you 4200 bucks on average. Yeah, try buying those with minimum wage!
