You only learn when you are doing something slightly above your skill level.
As an ascendant facing TenZ you will always get rekt no matter what you do. The skill gap is just too huge to learn anything.
I once watched a clip of TenZ smurfing with Kyedae and her sister in a silver lobby in unrated.
The opposing team was getting rekt, yet they were trying. There was a breach on the other team. He ulted TenZ, he got stunned. A couple of ppl peeked him, they both got headshotted. Or he flashed TenZ 100% and still got headshotted when he pushed.
You could argue that peeking when you are 100% that the other guy is stunned is the play 99.9% of the time. This will probably get you all the way through ascendant. But not against TenZ it seems. There is nothing to learn here. The breach played that perfectly. The skill gap is just too huge to learn anything. He just wasted 30 mins of his time.
