My better response to this:
Simple this just would be shit, ngl nor trying to be rude. All people would do, is sit in the nether and mic spam, make racist/disrespectful/homophobic comments and us staff will not be able to hear them so the rule breakers will just get away with anything to do in voice chat/text chat. It seems to me that you are saying, one staff member must to be dead AT ALL TIMES to stop these rule breakers which will be boring. We as staff are staff members because we like the game mode not to just sit in spectate mode. Keeping the voice chat system as it is now will be fine.
