@Antonio You're right, I've not tested those civilian Gunboats, but logically I still think they're still the total useless Gunboats in this game. Could you please tell me how did you judge that those adjustments made them balanced and how did you test them? Who took participate in testing them?
Anyway, we can go together and test them, all of those Gunboats and try in duels which are balanced and which aren't. Increasing the armor doesn't change much, neither decreasing the armor and the nanobots of Asco doesn't change much, if the Asco was so much broken, 10-15k less armor won't change things much, isn't it so? If Asco was broken, after these changes it will be still one of the most un-kill-able gunboat in this game.
P.S Duels isn't a case, so how do you judge Gunboats are balanced?
