There wouldn't be so much need for them to be repairable if they used hall effect analog sticks in the first place, rather than potentiometer-based sticks that are so prone to failure. That's nearly always how these controllers fail. Hall effect sticks cost a little more, but when they're charging $180 for the premium Elite controller there isn't really an excuse for penny-pinching on components.
