A feature request that would be a game-changer for load balancing...

Most often when a home user or business has multiple WAN lines, the WAN's may vary in downstream/upstream speeds. For example, I have two active WAN connections, one is fiberoptic, the other is cable. The fiber line is 1000mbps up/down (symmetrical), while the cable connection is 1000mbps down/40mbps up. In order to effectively load balance between these two types of WAN connections, it would be nice to have the option within the firmware to route traffic OUT (upstream) 100% through the fastest connection, while balancing downstream between the 2 WAN interfaces. 

Bottom line - independent load balancing control of upstream/downstream traffic across multiple WANs would be hugely beneficial, especially in cases where one WAN has significantly more throughput over the other. I understand WAN traffic can be balanced based on ratios, to favor routing traffic predominantly over one WAN vs another, but having the option to route all upstream over a particlar WAN (unless that WAN connection goes down) would be beneficial. 

Thanks for considering!
