I don't disagree with any of this. This is pretty much how I learned to stop worrying and love the d20 System.
We should still appreciate that not everyone will notice the same things, or notice them to the same degree. Something barely noticeable to me could be obvious to the person on my left, and completely invisible to the person on my right. (shrug)
I certainly agree that stats are
smaller numbers than before--but that makes your sources that much
more important, no?
When you can only get at most, what, a +13 on any given roll, and that only with
dramatic investment, every source of bonus matters. Especially since Advantage, while good, doesn't actually expand what you
can hit, it just makes you more likely to hit what you already could.
Or, if you prefer: If this is true, why do folks love to grumble about Blade Pact getting Cha to hit instead of Str/Dex? The greatest possible difference will generally be...one or two points. Especially if you're wanting decent AC as a Warlock. If an extra +1 or +2 is too small to be concerned about, why is it a problem to swap in a better stat in place of a worse one?
I see this a lot when it comes to 5e, if I'm being honest. Folks will downplay criticisms with response X, but then ignore or even agree with arguments that
require the logic of response X, just in a more narrow domain, or viewed from a slightly different angle. If +1 doesn't matter, then a bunch of things 5e actually does do are actually near-meaningless and the player should be right in complaining that they get nothing while someone else actually gets something. And if +1
does matter, then a bunch of other things are much more sensitive to problems than fans want to believe. If it were a true apples-to-oranges comparison, I'd be happy to accept that mechanic A doesn't really care much about whether you get +1 or not while mechanic B does. But we're literally talking about attack rolls and whether or not you deal damage--it's the same
thing either way, just depending on whether it's something special you got from your class, or something everyone gets by creating a character and levelling up.
