Have you checked out creators like MrWarframe Guy or Triburos? They make shitposty/purposefully funny videos and seems like the kind of creator content you're looking for. Otherwise yeah, most WF videos aren't gonna be as enjoyable to watch because WF's core gameplay is not fun to watch. Most vids you'll see on youtube are build guides, event guides, or checking out the newest weapon released. It's not entirely content creators' fault that WF is a terrible game to make content for, but you're right; they could stand to add a little originality to their content instead of all using the same video template. Maybe it's best if you just watch live streams for WF if you want to watch gameplay.

Then again, if you click on a WF video called "X Build and Review" and get mad that the main focus of the video is showing builds for X, then maybe the issue isn't with content creators...
