What you consider useless features may be others requirements. I chose to get a router without Home Care and would not use it if my next router has it. QoS, I might use if needed. I know Gamers use it.

Did you check System tools, System parameters? Is that what you are looking for?

QoS is so useless that you can't even target a device, you must "prioritize" the entire LAN, what would be the use of this? don't you have at least one Smart TV, one Phone, one PC/Notebook? so QoS Application priority will only benefit one of them, it supposes to be a "Home Care", what kind of home would be?

PD: I tested all this setting and there is no difference in the performance, delay, lag, response, it does not affect in any way the network, online games, Netflix, torrents, youtube etc etc..
