The player is limited to 5 Capital ships, which is increased by 1 for every planet he takes over. Warlords do not count at least, but you have only a few. Every time they die you have to rebuild their ship which costs credits, takes time and leaves them at your HQ.

I have seen the ai have huge amounts of dreadnoughts, carriers and battleships. It appears that no capital ship limit applies to them. The ai just spawns the ships, but you have to build each one. This takes time and is expensive.

It is almost impossible to capture a dreadnought or carrier early in a game even if you have done all of the research and have all of the related perks. Every capital ship you capture reduces the limit by 1, but allows you to go over the limit. So you need to build up to the limit before capturing the capital ships.

I would like to increase the initial capital ship limit and possibly double or triple the amount added to it for every planet the player takes over. How would I do this?
