I'm gonna be completely honest.
I do agree that the mute/ban system should be changed up some. It feels uneven, and sometimes definitely unclear. ( I know I can DM staff if I have a question about it, don't tell me)
One thing I'd like to see implemented with mutes, would be that you have to actually be on the gamemode you got muted on and moving around, while if you're not on the gamemode moving around / and afk, then the mute wouldn't go down.
Basically you'd have to move around and be on the gamemode you got muted on for your mute to go down.
