What i see that needs to be done to zm.

Cal doing that would make some escape maps virtually impossible to win: Deathstar escape, Lostworld Redux, LOTR...
Alltalk may be a slight disadvantage for humans and will cause more noise, it makes the admin's job easier making sure no one mic spams or for players to communicate with admins (most players don't know about the @ command).

i agree with dr tran for once, alltalk isnt a problem, u can still use team chat. i usually never hear anything over the mic in zm that would benefit the other team if alltalk was on
