I’m curious about the decision to require using half your movement to get up from prone. Seems odd if I have 30 it’s 15 if I have 300 it’s 150? How come a static number wasn’t used?Because we wanted you to use half your speed.

That’s not really an explanation of why you wanted to use half speed JC.
I love Jeremy Crawford’s answer. It made me laugh and reminded me of something I read long ago in an old book. Someone asked God why he wasn’t going to do something-or-other. His answer:
“There’s two reasons I’m not going to do that. One, because I don’t want to do it. And two, because I ain’t going to do it.”
