They're not only transports. My tens of thousands of certs whale is not a taxi. The closest allegory would be a hind helicopter. No, it's not meant to be a toothless transport. That's why it can mount weapons. It's meant to be good at infantry suppression. That's why the devs gave it bulldogs. That's also why it doesn't mount halberds. Just because you think galaxies should only be transports doesn't mean the devs agree with you.
