Shuri being a war dog wouldn't make sense. She obviously ain't cut out for that isht at all. She's fine being the CURRENT head of the Wakandan design group. The problem was that they have Shuri all the achievements. There would of been absolutely nothing wrong with Shuri getting credit for designing the new habit, or helping Bucky and Ross. The problem is when she then was given credit for being able to make vibranium inert when. Transporting it through the mines. That's basically ripping off when T'Challa stopped doom in DW war making vibranium inert. That conversation with Ross could of happened but given T'Challa the credit of figuring it out.
The new habit scene could of happened all the same but T'Challa talking with Shuri completely understanding what was going on. Instead of him asking what was going on with the new habit after he kicked it he should of instead immediately known it was the the nanotechnology absorbing and storying the kinect energy and said as much. Basically we are then as the audience, understanding that T'Challa IS a super genius, and the difference between him and Shuri is that he does not have the time to tinker
in the lab but has no problem geekying out when it comes to that stuff.
