Hey! This is a very hard question to answer, since we can't obviously generalize and assume that this is the scenario for everyone, however, - speaking from personal experience - most of the people I know either started playing sub-servers (such as prison and skyblock, as they've recently gone through a reset), and another portion of the players I knew are just playing other games until SkyWars comes back. Have a lovely day!
Murder mayhem was already dead way before the revamp. It’s been dead for more than a year. But skywars they either quit or moved to a sub server like others have said.
