So, the hangar changes are already being talked about a lot, and I agree with the generally negative response to them.
Carriers, in a traditional long-range strike force sense, are almost totally useless. The delay between launches is simply too long, far too long, for them to be a feasible alternative to a gunboat or even a lanceboat.
But I like the idea, I understand the intention. More launch bays=a longer cool down, but a larger strike force; while a less launch bays reload faster with the change, making light carriers less powerful but more responsive.
I think this change can still be made to work if the cool-down started immediately after launching the strike craft, as before, but with a much longer cool down for more hangar decks and an inability to launch a second wave until the first wave either dies or returns to the mother ship. I think that would much more effectively achieve the intended goal and keep carriers somewhat competitive.
