I am creating a separate suggestion in response to this suggestion. Rather than making it limited to playtime, remove voice battery limitation placed on non-donors, and give it as a power to staff to help monitor and combat voice spam. I made couple responses in that thread about why we should remove mic battery. You can look there and see some of my reasons on removing mic battery. Edited: I also included the option to remove mic battery entirely. The reasons why I believe it should be removed can be found in the linked suggestion thread.
