You're absolutely right that the Anaconda is over-powered and ideally should be nerfed.
However, as someone who has put a lot of effort getting my Anaconda over 60Ly, I wouldn't want to see that disappear. It's been in the game in its current state too long for FDev to change it without a considerable portion of the community being very upset.
there is another option...... the anaconda has a 400t hull. I would hope even those who are happy with the conda would agree that objectively that is simply silly compared to the hull masses of the other ships.
I agree it is not fair to strand folk in space however the alternative could be to reduce the armour rating of the stock anaconda to 20% of its current rating....... if you want to get its armour up you HAVE to fit the uprated armour.
if the hull is going to have the same weight of a paper mache balloon, give it the protection of one
