Epic is very aware that players might need custom matchmaking for a number of reasons. It might be useful for tournaments or parties, for example, or it might help certain streamers to grow their audiences. There are very few limits to the customization options once you have a key. The problem with custom matchmaking at the moment, though, is that it is very limited. Right now, the keys are largely restricted to major streamers and a handful of tournament organizers across the world. There is, however, a bright light at the end of this tunnel.
