But when a poster just wants to knit pick about different types of arrows not being in 5e, or jump not being in 5e, or height advantage (which I actually like if it is just ranged classes it affects) I just don't think that really helps development overall.
I think you're fundamentally misunderstanding the critique, here. The problem with everybody having firebombs/arrows is that they quickly make every combat exactly the same. That was the problem with everything making surfaces, combat became a game of high ground + spam surface effects. It takes any depth or strategy out of combat and makes it, honestly, a boring slog after the novelty of "big explosions" wears off.
