I find the per a Mk upgraded size of only 75m3 is just way to small...
Combining that with the INSANELY over priced $96mil for a mother ship optimization make these new mods pretty off limits to most players. Even a Class 1,2 or 3 ship with a small amount of cargo will require some pretty big Hanger mods. Especially if you want to "swarm" the target.
I would define a swarm as atleast 3-4 ships. And if your dealing with nests then you need the cargo space to actually pickup what you earn so that makes it even more out of reach to most.
I get the whole packed size bigger inside then out "Doctor Who" situation we have... Perhaps our cargo bays are inflatables? But still deflate the empty space when packing .
I can afford to optimize and build a good amount of hanger mods for a carrier or two but I would say all but 5-6 or so players here could make good use of these mods. I think it needs some reworking.
As the most expensive optimization you can buy I would think it would deliver more then it does as of now. That $96mil could easily be spent on Science mods to research high Mk hanger bays (which also gives you new tech opportunities forever) and build them and you would still come out ahead for less $$
I just think its way to expensive for so little reward. If we can fit an entire gas giant of mats into our cargo hold then we should be able to fit a couple of ships with empty cargo bays.
