I was testing new expansion yesterday. Settings were:
-100 planets + 10 nomadic planets.
-Vanillia 7.0 and Mimic 8.0 AI types.
-Neinzul combat carriers as my bonus starship.
The game ended in one hour. I was expanding peacfuly, captured few planets, cleared and captured one nomadic (those nomadic planets are great by the way. It is nice to settle one, and look it floats toward AI homeworld..).. AIP was 80 at that point. And then i decided to besiege Mimic's planet. My fleet entered the sector, and cleared most of it. My combat carriers and enclaves were spamming with drones. And when there was only one guard post left.. Mimic responded to my assalut by sending reprisal wave at my border. The wave had 3k of ships, what was.. 30 times more then the biggest attacks i had so far, and 10 times more then my defensive force was. I moved everything I had to defend my border. When the wave started I noticed 2200 AI ships are neinzuls. I felt calm and solemn.. and then AI fleet engaged my defenses. Neinzuls cut through everything I had in 3 seconds. Exactly 3 seconds. And then decayed, and remaining 800 ships continued to advance toward my homeworld and eventually destroyed it.
Conclusion: never attack Mimic using swarm neinzuls. Especially combat carriers' drones, as those are totally imba, and should be nerfed.
And by the way, combat carrier's description should contain info why are higher marks better, like enclave ships.
