I think /ma Wave should be a command because people might be waiting for the mob arena to finish and its good to check the wave, I think this would all around be a good command. Look at this picture for example. Sorry Can not load the picture
Support it wouldn’t hurt and would only help then someone in the middle of ma having to stop and respond in chat
Support if it's possible to be added though. Sure you can always ask around but not always someone will answer you and you can also spectate (/ma s) to see which wave they are in.
It's really annoying having to go to the mob arena and interuppting whatever you were doing just to check the wave of the mob arena full support
