I feel like with how controversial some changes are and how polarising some others have been after release it would greatly benefit testing and balance efforts to open public experimental servers similar to how you see them in other games.
Features that are controversial can be created and tested on these servers before making the judgement whether to add them to live servers or scrapping them entirely. This would be an extremely time consuming addition but in the long run would benefit the health of the game, the devs and the community at large by creating a controlled testing enviroment for feedback.
