I have lost count of how many people complained about not being able to raise their endorsement levels, or having their levels drop as fast as they raise up. They think it is a bug or that the system makes no sense. Never realizing that it makes incredible sense, they are not bugged, and the entire reason they struggle is because of their own bad behavior. I’m not talking about being reported (although you lose endorsements for that too). But some other bad behavior that is far more widespread.
Being impatient and leaving the game early.
I know what a lot of you may be thinking after I say that… “But wait, I don’t leave until after the Victory or defeat screen!” or “But wait I only leave during the POTG clip is shown!”
Guess what? You are still leaving early. And you are still losing endorsements because of it. Do not leave your match until the 4 player cards get shown and miraculously your endorsement levels will stop struggling.
There is not even any reason to leave earlier than the card handout screen.
Even before the endorsement system was put in place there was no reason to be impatient and leave early. But with the advent of the endorsement system it is more important than ever to wait until it is safe to leave.
The code that removes endorsements if you leave early is not removed until the game’s central server receives the information that the game has ended. If you leave before that acknowledgement by the server that the game has ended then you still get penalized endorsements the same as if you left mid-game.
So people learn to be more patient and wait for the serve to receive the notice that your game is ending.
