It should be understood why they were T1:
- TA memes. The fabrication equivalents in TA are T1 and T3. And in TA Mass is alot less plentiful.
On a basic level mex points, provide often an average 1 mass a second. Also things costed more, like alot more so. (About 50%-66% more raw mass. And almost triple raw energy costs).
Also I’d need to double check, but the other aspect of Fabricators in Supcom Vanilla like TA they costed 0 mass.
