I still don't think reflect is a problem. It is insanely hard already to actually deflect stuff back at people, nerfing the box is just going to make deflect even harder.
I've said it before and I'll say it again, no one ever complained about deflect before they saw that video. Just saying.
It's funny , before this was brought up, at least that I know of, I had a match a few days ago where a teammate brought it up. He aimed a rocket at a Mei and genuine was reflecting someone else but just happened to be close enough to the mei that the hotbox, which the visuals don't match at all, threw it back St him.
Since then I've seen it so much now that I'm aware of it. If people aren't complaining it's because they just haven't noticed. Which doesn't mean it isn't poorly designed.
My biggest gripe across the board for this game is hitboxes being significantly off from the visuals. Just change the visuals to match at least so it feels fair and not cheap. Seriously even make the hand arrows bigger or give them some wind or technology electrical glow effect so people can see fairly what it's range is, who cares if the arrow looks silly big, they have great artists that can figure out some solution that doesn't look that bad.
