So far the stupidest thing so far is 2. keeping Idira alive, and 1st. Leeting Jae join the crew.
I should have listened to the rest of my retinue, they are actually reasonable.
I usually keep all companions I can just out of curiosity to see their content, even if I know I'll be meh on them.
I am fully expecting to hand over Idira to the inquisition first chance I get. She seems like a completely pointless character.
Yrliet I get the idea of, though it sounds like her implementation is less a clever scheming teaching you that you should know better than to trust xenos and more like constant and obvious betrayals that makes you look a complete retard for even considering her inclusion in the entourage
