In most packs, it's 2 steps more, give or take.
Honestly, Vazkii has a great mod that a lot of people love. Her design choices lately have been terrible though. She doesn't want us (lazy people or people who aren't going far into the mod) using passives? Ok, we'll bum rush thermolillies or the coal burning ones, and use NOTHING else. Most likely, it wouldn't even get automated. It's just switching one set of flowers for another (1 or 2 step more) flowers. It's not promoting diversity, it's just taking it away.
Well seeing as Endoflames are the 2nd flower you make (if you only make dayblooms, and not nightshades), the "coal burning" flowers aren't exactly hard to get.
As for the Thermalilies, yes, you're bum-rushing them. But at least you are using something that requires SOME effort.
Even if you had Rosa Arcanas all around your base, so whenever you walked up to your AE system, or your furnaces, or whatever, your XP becomes mana. It's not something that anyone would call "easy" to set up. But as soon as it is set up it's about as passive as dayblooms, only requiring you to be in your base, near stuff that you are always near...
No, it isn't a replacement for FREE mana, but it is still pretty simple once you have set it up (and remember, these can be under the floor, so the whole layer under your floor could be Rosa Arcanas.
Let's get back off that tangent...
Thermalillies are one of the few flowers which can quite easily be automated and run from RF (through the use of a few machines), so I understand why people use them. And if you only use Botania for a few things; sojourners sash, flugel tiara, etc. then I can understand people only using thermalillies and/or endoflames, as they are pretty simple, and easy to use.
And, and I can't stress this enough because this seems to be the core of my annoyance, want a flower garden, that looks like a flower garden, including things that I can defensibly call flowers.
Then just make the motif flowers, or use the ones that spawn in the world, and have your generating flora hidden away?
It would have been a lot smarter to limit the spamming of passive flowers by doing something like Reika did in RoC to prevent spamming cheap engines. If more than 4(I think it's 4) engines feed into the same shaft, they don't work. Vazki could have limited the hardcore spammers by imposing a hard limit on passive flowers in a certain area or set a hard cap on how many could connect to one mana spreader. This would have prevented spamming passive flowers while not hurting players like myself or Chris Becke who just need a little mana from time to time.
This would work. However, if someone wants to make 10+ dayblooms for their initial burst of mana to get started in Botania, I don't think it is something that would work, and I doubt Vaz would want to penalize the people who want to get a decent amount of "starting mana"
