Probably to make it feel more realistic. It would be strange if you could fall 50 feet and only take 17 damage
Eh, there are different kinds of simplicity. My big problem with 5E is that it puts so much at GM discretion without any strong guidance than it feels like a completely different system between one GM and the next. This does in fact make character creation (and to a lesser extent gameplay) needlessly complicated because what constitutes an optimal (or even reasonable) character depends heavily on which rules the GM is going to choose to use.
Idk, there was an expansion released like a month back so it’s probably experiencing a spike in popularity.
Also if you don’t know I’m alluding to the fake season names it uses which are portmanteaus of real month names. Decebuary, Aprimay etc
