So, what is the problem with extreme mass ships? They are as nimble and as fast as a fighter... The new thruster update will fix this hopefully, so I am not about to talk about that. What I will talk about is FTL, and how to balance it for these big ships.
The bigger the FTL core(made out of FTL blocks) the longer you can travel at FTL speeds, however, the higher the mass of the ship is, the slower the ship goes while at FTL. For this system to work we need to measure speed in sectors/s while at FTL. This would allow use to say where we want to go, and activate the FTL, and have a timer come up for how long it will take. If you don't chart a course, it just says how far you have gone, and when FTL will end(you can cancel it manually).
This system allows for high mass ships to travel at FTL, while limiting the distance they can go. This adds downsides that are not currently existent.
