Not saying that the premise of the story itself wasn't forced and stupid...XoS was contrived, bloated crap from the start but...in the context of the issue and what it was mandated to do, it accomplished just that.
Storm goes to Wakanda. Politely asks for the sword. Is denied for dumb reason. She steals it, knowing the consequence of doing so. Is caught by Shuri. They fight. Storm wins. T'Challa shows up at the very end conveniently. Trust ruined. The end. Keep in mind that up until that point no one knew that skybreaker existed...it didn't. So yeah, contrived AF. But the point was to further drive a wedge between Krakoa and Wakanda for some far off plot that was never realised. Enh.
