@Leo_the_Lion25 Actually this situation is rarely to see but I think that it is quite fair to let the gold knockdown shield users to stay alive even all 3 people are down.
Lets take an example of the following situation: Supposed there are only 2 teams (you and other team) left in the game and both of the teams are in Singh Labs Interior, except you are at the top while the enemy team is inside the lab. The round 7 ring forbids you to fight them as you will die while finding a path to enter the lab. Unlucky, your team does not have a wraith while the other team has. Then the result is obvious: your team loses as wraith can use her ability to stay longer in the final ring.
In the above example, can we say that wraith is broken as she is the only one who can stay in the ring for a little bit longer? No, as this is what Wraith can do in this situation. You lost as you are a little bit unlucky about that, so does the gold knockdown shield. It designed to prevent the team dies even all of the members are knocked, if you really want to complain these particular situations, then you should complain all these situations (such as a caustic using his traps to block the door completely while you don't have any explosives, or the situation I mentioned above, something like that etc).
However, I know that it is really unfair for teams who were the one who knock down the whole team but they didn't get any points. I think there is a solution, that the game should allow the gold knockdown shield users to keep their position point, but the team who knockdown the members from them can still earn points even they died before the gold knockdown users get killed (without being revived during the process). This will keep the advantage of the gold knockdown shield, but still can make the game fair.
I am sorry about this comment maybe a little bit messy to read.
