2V8 on kyf only until game suitable for two gamemodes (a little long)

so basically i want the ability of playing a 2v8 in a way that the devs can contently monitor and not have to worry about all that much so my idea is to make 2v8 a kyf only mode that allows people to experience it but not effect the main game in any negative way so the way i purpose this is by adding 2v8 on kyf as a sorta creative mode like in minecraft were people can test things about the mode and also find things that could help improve the devs progress in making the mode a reality also after every kyf of 2v8 there could be a little response link that you could click and you could tell the devs how certain things work and how buggy it is and they could look at these bugs during the release of a chapter or build up and implement fixs when ever but not to the point were they have to ignore the main game sorta like how they talk about how they would run both dbd and death garden
