Yep, obviously.

Cant see how that would do much at all.

That neither.

Not sure what you're refering to.

I really only skimmed once over the PHB so I also dont know what this refers to either.

For good reasons basically every DM has house rules.

No computer game EVER has implemented any D&D ruleset in full and its not even a good idea doing so, since not all rules are a good idea in the first place.

Adjustments to make the final game better are thus perfectly in order.
