The cost per roll was the same (unless the blueprint needed cargo and many did), but for much of 2.1 materials dropped in quantities only a third of what they did later. Experimental effects were also only on ~10% of weapon rolls and there was never any guarantee of getting a good roll. On average, getting to a given grade probably took as much effort in the original system, and getting something distinctly above average was typically far more labor intensive.
I said effort, not cost. Even in 2.1, the amount of effort required to acquire a single G5 roll also yielded several G4 rolls, and many G3 rolls, and you didn’t have to go through the intermediate steps to do so. In addition, pre-FSS the ideal route to your destination practically guaranteed an encounter with a HGE, and that kept me swimming in mats, even before they increased the capacity of our pockets of holding.
The worst thing about the new system, IMO, was that they didn't forcibly convert old modules, so had to inflate bonuses to make anything created in the new system competitive with the best of the old stuff.
Agreed.
