Sorry, but I found it very hard to take your post seriously after the first sentence. Asps, Pythons and condas prey to everything?
For now I will assume you were being sarcastic...
My combat Courier with double chaff against your small-shield trader Conda without shield cells, okay?
Any ship fitted for trading can't realistically defend itself against a combat fitted ship. The only reason the Anaconda doesn't mind is because the shield is still fairly strong due to shield boosters and highest MLF in the game.
I think things are pretty fair. Why would traders be more survivable than equally sized combat ships with stronger armor and shield emitters?
Why are the shield "emitters" stronger in combat ships again? I'm installing the same 5 million 5A shield generator into a Type 9 as into a FDL, yet the FDL gets three times the shield strength out of it.
Some people have said that you trade more trading power for less defense when you use a Lakon Type trader, but that couldn't possibly be further from the truth, as Lakons are not that much better compared to the equal size multipurpose ships the game has now
The Hauler (as obsolete as that thing is anyways) has less cargo than the Adder and is inferior in every single way
The Type 6 has less cargo than the Asp (I realize they are quite far apart, but with mission income what it is now, that gap is crossed a lot faster than it used to be 9 months ago, so Type 6s will last new players for a few hours only)
The Type 7 has less cargo than an Imperial Clipper and is just equal or inferior in every other aspect
The Type 9 has 10% more cargo than the Anaconda, but the minuscule jump range prevents it from using many good trade routes.
The balance question here is very simple: Should trade ships be free kills for combat ships? That's pretty much exactly what we have right now. High waking will save you from small fighters, but if your type 9 gets interdicted by two FdLs, you're dead before those 15 seconds are up, and that's 10 million credits poofing.
I've always proposed a significant cargo capacity buff fo pure trading ships, it makes no sense that they're maybe 10% as formidable for combat as a multipurpose ship, while not having any sort of cargo advantage over them. Pure combat ships definitely do have advantages over multipurpose ships when it comes to combat.
So buff what they're supposed to be strong at, add cargo to all of them. Type 6 + 64t, Type 7 +96t, Type 9 +160t in max cargo capacity.
Another thing is discounted insurance. You all know this from RL, your Porsche is a lot more expensive to insure than your family van. Because risky driving is associated with the type of car you drive. Trading ships do not actively seek combat, therefore it makes sense to have them pay less on insurance. Given they're already losing an entire cargo hold on death as well, it's actually the other way around right now. Dieing as a trader is far more expensive as dieing as a combat pilot.
