I would actually add that Shuris design potentially has a pretty fatal flaw as well. Yes the habit can be fit and taken anywhere and be inconspicuous, and we don't know how T'Challas suit is out on however, once the battle starts, if anyone knows how it works shuris design can be taken off in combat and they become defenseless. As we almost saw that happens to Erik had the suit not been powered by the Spears they would of succeeded.
