which i'm pretty sure for this one is in the DMG not the PHB, why not kick up about the encumberance optional rule, or that if you get disarmed you can pick your weapon up for free which essentially equips it without losing your action, or that hiding is an action, not a bonus action, or do you just complain about optional and house rules that are negative.
As mentioned, it's not, and you're mistaken, unless you'd like to cite a reference.
(I just read quickly through the entirety of the dungeon master's workshop section of the DMG, which is where it lists all of the suggested optional rules including ones related to ability checks, out-of-combat effects and running combats as well; there's no mention, anywhere in the chapter, at all, of rolling a 1 or a 20. I can't exactly quote the entire chapter to you, and I can't quote the 'place where it doesn't say it' because that's everywhere... you'll need to quote the section, if you are adamant that it exists.)
Actually many folk here have been giving feedback for along time about various Larian homebrew, positive and negative, and offering harsh feedback where it upsets game balance - shove, you might be aware, is a particularly contentious one, in fact.
