My suggestion is introduce Shivs again, obviously everything depends on the Big Studio to create them. I understand that in a long war where many soldiers are constantly needed, robotic allies like these can help us to complete a group more easily. Apart from their skills, they can support with medium cover.
Also they can have a great survival using Smoke grenade, Aid protocol in them and can be repaired by the Grenadiers (Engineers in Xcom 2012)

About as evacuation missions in high areas of buildings, could be solved adding propulsion system to the Shivs (after all, 20 years have passed since the last war, technological advances could have made it as possible perfectly), or Shivs directly near to the stairs be allowed to climb without animation, or adding Hover Shivs (Flying Shiv version)
This would make a game more extensive and entertaining and would continue more faithfully the main story, where years ago shivs were used on the battlefield, why now they disappeared?
Thanks!
