Ok, apparently I touched on quite a nerve here.

1.) I never said you don't need UX designers, I said you don't need UX designers to tell you that your video shouldn't stutter in the middle of playback.

2.) I didn't downvote you, nor did I respond to you.

3.) Yes, exactly. They can tell you there's a problem and monitor whether it's being solved but it's up to the engineers to fix it. Furthermore, I reject your implication that engineers nor anyone who isn't a UX designer (e.g. a PM) is sticking up for the customer. I wasn't belittling UX designers, but you're sure as hell belittling others.

Sorry you have had such a bad experience that you need to attack a strawman to stick up for UX designers. I know the value of UX designers. I stand by my opinion that they don't need to have ANYTHING to do with fixing a video buffering problem, or recognizing that it is a problem.
