Why not? You feel you should be able to do everything yourself without the need to buy anything? You already can with the right set up. You can also buy them, if you don’t want to then you make them yourself.
And you do not need to buy specialised tools to gather shimmering orbs, I never did when I started making pies and brews! And I couldn’t forge myself back then either.
Yeah but here’s the thing! Do you want shimmering orbs, glow lamella or the plant?
Those are 3 different things. Shimmering orbs are very, very easy to get, even with an unforged silver shovel.
FireAngelDth and I just opened a portal to his shimmering orb farm on Dzassak, it’s a Lvl 1 planet, completely safe except for the water, go there and you will get some.
Okay, you need a regen bomb, those are the most easy to forge items there are, if you can’t yet, well, ehh, buy them.
If you don’t want to then yes, you have to go out on Lvl5+ planets and try your luck at the glowcap fungi.
But why not simply buy that regen bomb for 799c I sell them at? Plenty of stuffs you can sell to get that amount of coin. heck, go crazy and buy a forged 3x3 silver shovel from my place for 1899c as well! If that’s too expensive, well, ehhh… Wait until you need to gather forging mats! 
Mja, that is the problem then, you refuse to buy the tools you need in order to gather more and easier. And if you can’t make those tools yourself yet, well…
For crying out loud! Then SELL those! To me for instance! Then buy a regen bomb and a forged silver shovel and go to the Dzassak shimmering orb farm!
It REALLY is that simple!
If the drop rate goes up, price of shimmering orbs will go down too. New players can NOW already sell those easy to get spicy beans, leaves and pulsating orbs…
