Well, I suppose a ton of people complain about the engineering for some reason. I never quite understood the reasoning, as it just sounds like "I need to grind the game in order to get the highest-grade endgame stuff". Something that's quite common in MMOs. What exactly are they expecting? Getting all the highest-grade stuff from the get-go without any kind of effort?
Yes. I think this will be the reason why we will now get "balanced" engineering in such a way that it will be almost impossible to do with just in-game activity, but really easy to do with ARX. This will help the game by means of generating income for FDev. And it will give those "i want everything now" dudes a way to do it: by paying.
One way I can imagine it being achieved is by actually increasing the mat costs in ship-engineering to the level of on-foot engineering, while simultaneously removing the - now largely comical - "gambling" part. The next thing is the x3 drop of material gathering. This might be reduced to x1 again. Similar to on-foot engineering, G5ing e.g. an FSD for increased range will then take weeks, not hours. If the RNG drop-rate for higher-tier mats is then also reduced to what we see on-foot, the scheme is complete: painfully long grind for almost essential engineering, thus a strong incentive to buy e.g. a material package with ARX.
Now, instead of making one big drop of that hammer to the community, do it in fine doses in order to avoid critic. Everything above can be done one after the other. E.g. first remove the gambling part, just increase the mat costs a little bit, let's say where you had to do 4 rolls with x1 mat in G4 before, you now need no rolls, just unlock with say x3 mats. People will be happy, because it looks like a net buff, and it removes the hated random part. Then, after some time, "re-balance" and remove the x3 dropping to the x1 dropping. Might spark some critic, but that will quickly fizzle out. Then increase the mat cost bit by bit, like in that G4 recipe, just add 1 for a x4 mat. Later on still, make the "rare" mats really rare like e.g. opinion polls or SDPs.
Concurrently to this plan rolling out, populate the store with convenience offerings, like fully engineered modules, material-packages, or even gambling elements like e.g. 10 free random engineering effects for just 10k ARX.
I think this would maximize income, while still keeping most of the community.
