Let's decide what a rating is? How often can your pets die? And how much gold did you spend?

I want to suggest several changes in the system.

Let's start changing the pets
Why not make the range of attack as the master. 10m range so small - sorry ><
I'm really tired of calling a dead pet so he died again in 3 seconds (I mean aoe boss)


And now the main thing! What does the rating do? How does it help? Is it useful?
I want to offer a settlement system. Now is random. Hero Rating dont work. I want a real rating calculation:

Blue Team
1 hero - 2567
2 hero - 4014
3 hero - 2025
Total [8606]

Red team
1 hero 2600
2 hero 2140
3 hero 4260
Total [9000]

Of course there will always be errors and I understand that it is impossible to track two identical classes, meaning a healer/tanks. If you explain how the rating works, or is it stupid? I do not want to think that the rating was created for bragging.

And a small addition to the auction. How much gold was spent in the history of purchases for all time.
