Back then the discussion focused mostly around the teuthida and strategic reserves. Now, considering you altered the teuthida and the fact that it needed alteration spawned from me posting it (noone else posted about it being mostly imbalanced at that point) you might consider taking a look at the gatlings (at the very least) too.
My memory may be faulty, but I believe it had been brought up before then, but a detailed look had not really been taken. My changes there were based on Diazo's feedback later on, but thank you for weighing in as well.
I think its rather obvious (insane range, dps, rof, they can repel most waves on their own w/ grav turrets or kiting and can raid like a king. 400k dmg ?)
Well, as you can see by the following two posts, it's not just a matter where you're the only one bringing it up (fwiw, you're not the only one to suggest the gatlings could be OP), but there are experienced players who actively disagree with you. I'm sure you can see that my simply taking your word for it, however emphatically you may state your case, isn't the solution.
Personally I have no objection to nerfing them, or to buffing them, or whatever sounds reasonable. Most balance changes are quick and easy. But first I need to see some kind of consensus or other good reason to do so
