I noticed this as well and find it pointless to worry about which officers to use if you no longer need to look at their attributes, like memory or their type, like astrometric scientist. They need to bring this back in. I enjoyed spending the time to look over my doffs to get the right ones for missions. Like to stated, they also need to make it so the success for failure percentages rise or drop. Right now most of them are 54% success 36% failure, etc and don't move regardless of officer you use.
