Why is there even a performance test before you can play multiplayer if it clearly does nothing to prevent people from lagging, especially in 4v4?

Its completely ridiculous how one guy can make the game run like a sladeshow and not even be bothered by it because he probably isnt even aware of how awful it is compared to playing without lagg.

There should be a stricter performance test that you cant cheat and consistently causing lagg (which is even detected by the system since it gives you the yellow/orange clock) should force you to retake the test if it keeps happening or ban you from multiplayer if you keep cheating the performance test.
