Whats wrong with you Sindroms? You keep posting on buffing the transports constantly?
I say I'm fine with that if you lower their cargo capacity.
You want a gunboat gun and 2 missiles? Sure, but lower the damn cargo by 1000 or more. Those things and new power cores and personnel (and rooms for them and those things) need space.
Personally, I feel like transports are greatly protected.
If you want to trade hastely and freely - use damn whale or bumblebee or something like that.
If you want to trade big but trade slow and unprotected take the 5k trains corporations offer.
If you want protection try the Shire or Akegata or Alg Mover or something like that. Lastly, hire those damn escorts. It's really really easy to avoid a pirate gank squad if you have a lvl 30 freelancer in front of you scouting the way.
Trader ships come in many sizes and shapes and offer different approaches to the situations.
I didn't hear that a bomber managed to take down two shires before they could dock.
