As we all know rocket animation is bottleneck in endgame and there is no way to speed up production. Because of that modules/beacons/legendary silo makes no sense here.
I've seen suggestion to speed up animation but still I think it won't be enough and wouldn't look good. We can reach over 50x base speed combining modules and legendary silo and +300% productivity so building 50 parts can take under 1 second I guess
Speeding up animation 50x would look bad.The other suggestion I found was to increase capacity of rockets and increasing their price. But this can lead to slow mid-game when rocket parts are expensive and sometimes we need to send just few items.
My suggestion is to "merge" multiple silos into one. Just like we have 3 types of assembling machines we could have another type of rocket silo. Let's say it's a grid 3x3 of 9 merged silos so speeding up would make much more sense here. I imagine there would be one internal "builder" that supports all 9 silos and we could speed up this builder much more than we can currently. In addition, those merged silos could be a bit smaller than default one but more efficient, sending rockets much faster (10-15s animation).
