The idea of insane tartarians is fun and thematic but would add even more randomness in endgame if it works like standard insanity.

Actually the lucky guy getting some tartarian commanders (20N discount to use them) without too many afflictions can have an huge advantage. With random insanity in addition a lucky player will have one more huge bonus when other's tartarians become mad.

So I'd prefer a not too random system, with choices giving more chances to keep control or not (an idea : special insanity with % based on gem value or research level of items carried ; the more a tartarian recieve high level items the more he feels powerful and risks to become unleashed and claim godhood for himself). Then it becomes a strategic choice to take the risk and gear a tartarian with artefacts etc..., or use them with just their built in items to be sure to keep control (but making them more vulnerable of course).
