Problem
T3 Mass Fabs are weak as it is, lacking a clear role with T2 Mass Fabs being more efficient and RAS SCU's offering more utility. T3 Mass Fabs can become the easiest late game eco option by this change, and possibly result in more explosive (=interesting) bases.
Solution
Integrate T3 Pgen into MassFab by simply adding 3/5s of the Pgen cost to the MassFab. Now, people can simply order engineers to build lines of T3 Mass Fabs.
T3 Mass Fabricator
Build costs:
- 120,000 E --> 155,000 E
- 4,000 M --> 6,000 M
- 5,000 B --> 9,000 B
Yield
- -1,500 E --> 0 E
- 16 M
The same will not apply to T2 Mass Fabs, as they are already the better choice.
Justify the Solution
With T3 Mass Fabs not draining energy they are easy. If you don't care to optimize you can just take a T3 engineer and draw a line of T3 Mass Fabs without worrying about power stalls. This will make this easier than making RAS SCU's.
T3 Mass Fabs with integrated power will cost significantly less building space so the building has a better payback per build area. However, unlike T3 Pgen + old Mass Fab, you cannot turn off the Mass Fabs to get more power to resolve a stall so you also lose some utility. - I think this balances out.
While easier to build, with lines of T3 Mass Fabs, they are also easier to destroy especially if you really do build continuous lines as the buildings are volatile. Hopefully this will also result in more chain explosions.
