Navigation is a very useful trait,
Navigation + coding is better. Good quality computers will boost both our research and production and gives us an option to use robots later.
This seems premature, we possess the capacity to defeat them on the small scale, and are not capable of a large scale engagement.
I want to have a force that can defeat a division worth of enemy as soon as possible, allowing us to get noticed and having enough time to adapt to that and regroup before humans will send a huge force
Also, I want smart soldiers, as i want this Soldier to be fertilized next turn and mate with commander or queen. That may give us slightly less fight capable soldiers than standard S-caste, but I'd like them to fill the role of combat engineers that can be quite useful between combats better weapons\fortifying our bases
A mind queen would be far better suited to such tasks
I am not sure that we need a mind queen, a lot of tech drones can research quite effectively, too. Wasting loyal queen spot on R&D looks like a waste. We can get several high level drones, clone a lot of generic tech drones and build R&D computers to get the same effect
We have no need for a mind queen to create R&D caste, there are more cost effective ways to do that
I really prefer a queen optimized for farming, or war queen, or deep queen or electro queen, or vacuum adapted queen... Such queens will influent their children in funnier ways allowing us to create very useful subhives
