The problem is partly that “skill” is not as clearly defined objectively as “boss defeated” or “player died”. It’s very hard to look at wave statistics and decide whether something interesting happened there. I am tweaking the algorithm on a daily basis to try and improve the situation. Speaking of which, there won’t be any “skill” highlights today because I made yesterday’s criteria too strict and nobody made the cut. 
The other issue is that highlight video are primarily made to entice new players, and in that respect it doesn’t really matter if it really is the best-of-the-best.
I considered this, however on portrait mode there isn’t enough space horizontally to fit everything in. I could have a custom HUD for videos, but that would take considerable effort.
I’ve made some changes to the camera panning algorithm to improve this.
I’ve now removed this wave from videos.
I don’t collect enough data to do this currently, but I’ll look into it for v.145.
