No, mumble is about dynamic communication. If you want to split your squad up into several smaller groups and have them communicate effectively without blocking each others' comms then you use mumble. If you link up with members of another squad you use mumble. You can temporarily attach people who aren't part of your squad but are waiting for their squad to get back, move with you to link up with their squad, or working with your squad because their squad is down at the moment, etc.
Mumble should be your main channel of communication unless you need to contact your squad in its entirety, at which point you use in-game VOIP. Mumble provides local situational communication. You can call out a target using the compass and people will know which direction to look, whereas with in-game VOIP two people could be in completely different positions, making the compass less useful. Comm channels aren't flooded by people talking over each other and they can communicate much more efficiently.
With a 1 channel system all of that just goes out the window, you can barely use mumble at all and it loses 2/3rds of its potential uses. You're better off using TS. What happens with 1 channel is dead people spamming to confuse and annoy the other team, teabagging and other assorted retardation, and just general stupidity.
