Or you dont have 30 devicesNeither would I but it is simply not a problem with a 1gb connection. Monitoring traffic it becomes obvious that the line is never saturated so there will always be bandwith for any of the scenarios you mention. They simply do not happen. And even if one client should somehow find a magic server that could deliver a data at "full speed", all our connections are wireless the throughput here would be limited by this.
I have always used QoS in the past but after getting a 1 gbps WAN connection it becomes obvious that it is not needed (yet - in a few years this may be a wrong assumption).
