It IS slow but by the time you have the infrastructure and technology to use them you also have fast engines and solar sails. If enemy wants to fight he has to come to me, I just destroy his planets. I can fit a repair bay on a baseship and still have plenty of space for weapons. This makes baseships almost immortal.

And the baseships can have most % of weapons and shields on them. They have only 2 disadvantages - slow speed(not so imporatnt in strategic combat) and they are easy to hit(but they have many shields and much armor). BTW: If I remember well the "average" BB in hi-tech games cots about 24 kT of minerals. BS about 36 kT. 2 BB's have hard time beating a BS and they cost more. These are the reasons why I prefer BS over BB.
