I've been working in Arista TAC for more than 4 years, so I've seen a lot of customer network configs, and you know, exactly once have I looked at a customer's QoS config and thought "yes, these people understand the concept of QoS and this configuration makes even a tiny bit of sense with respect to improving their quality of service without opening them up to a plethora of other, more painful, issues"

Just buy more bandwidth.
