Talking with Darkant, it seems the three homeworld start is the big influence.

Too much intel production for the amount of infrastructure you've built up.
You will definitely want to work on building up your BSYs.

The more construction infrastructure you've got, the bigger you can make your warships without falling behind in numbers.
Definitely try to get a SYS to your warppoints... Use it to build a small BSY, then have the small BSY to build a bigger BSY, and so on. Soon you'll have the constuction power to build a hearty array of awesome defense bases.
