"Cant understand the logic behind it at all."
If answer = yes then discard data.
If answer = no then record whether or not player immediately re-queues.
If answer = yes then churn = 0.
If answer = no then churn =/= 0.
If churn =/= 0 then Problem Exists.
If Problem Exists then create ludicrously overpowered legends and other game-breaking features for next season.
With a data-driven company like EA it's pretty easy to know what it is that concerns them. It's $$$. When the data says X and revenues are falling off then X is the wrong answer. If the answer changes to Y and suddenly revenue starts to climb then Y was the answer all along. The problem is that there is no Y in a six year old game. Mathematically impossible. But Respawn, in order to show that they are "addressing the downward revenue trend," will continue to chase after Y with things like ASH and damage reductions for players holding an LMG. It's like beating people with a whip and waiting for their morale to improve.
