I've honestly no idea whether this has been suggested before so forgive me if it has...^^
As someone who loves making videos I would enjoy an option to join random servers as spectator in order to be able to record videos.
If you were to record something right now, the best you can do is deactivating all of the UI and record videos from one single perspective (your own). There could be so many cool videos/machinimas of the game as it theoretically offers so many great things/ideas. Not even talking about a full-grown video mode where you can record character movement etc (like in GTA V), I would be happy with things that many modern online games offer (Free cam, attach cam to certain objects/bones, camera settings etc etc.)
I understand that this is probably not very easy to implement and that this kind of feature appeals to 0,5% of the playerbase, but I still think that it would add great fun and opportunities for content creation.
