Get a guild or friends to queue with, you'll see things from a different perspective.
Separating solo queue and group queue is already existing in ranked.
Doing it on potential 8v8 regular warzones would make waiting for a pop last forever without server cross queuing (which will NEVER happen)
Gear gap is almost non-existent compared to what is used to be. You can actually perform well with a few conqueror pieces and more than half a brain. And that with every single class, provided you know how to play them.
The balance is not so good, you have to adapt around it. At least that's what good players do.
If you get stomped and are frustrated, man up, learn from your losses, and get better.
