With such arguments the discussion is unfounded ,good luck.
What arguments do you need? dead zones can be seen when you adjust the axis of the joystick.
I see a 15-20% dead zone in the center! or do you think I'm trying to joke?))
about buttons - I prefer to use a minimum of third-party software, and in order to reassign buttons I prefer to quickly go into the "options" and do it, rather than close the game and set up a remapper! And yes, I have been using remappers for 6 years now.
