besides all that has been already mentioned, the objectives are not always clear and are not updated in the ( i ) objective button. I had a good time at challenging difficulty level but in the map "we've run into a bit of delay" it is unclear what the objectives are next. Keep kicking ork butt or save the maximum possible amount of units. I've tried both exiting leader on the designated area along with other units but I get the message "imperial guard surrendered". The game could benefit a lot from a decent patch.
