Yes, there are still modifiers. However, the modifiers
do not work the same way anymore. They don't apply to the same things or in the same way (for instance, there's no damage multiplier). Also, when is that Toady quote from? And what are the multipliers for the OTHER quality levels (we just don't know)? And does that also apply to weapons? And how? The fact is that these modifiers are necessarily going to be different for the new version since damn near nothing is calculated the same. You cannot simply assume that they're the same ones as before, and even if they are, we
know they don't affect the same
things as before.
Basically, you saw "there's still some sort of quality modifier for armor, and it's 2x for masterpiece and 3x for artifact" and took the unwarranted logical leap from that to "the quality modifiers for armor and weapons are both the same as before and serve the same purpose as before as well" (which we know for a fact is not true).
First off, you copy-pasted a *lot* of stuff, not just the table and the modifiers in it. Christ, you copied over damn near the entire 40d article, and made it pretty clear that you didn't bother verifying any of it. So it's not just about weapon/armor modifiers, it's about
all the content you copy-pasted over, which
is something you aren't supposed to do in the first place.
Have you noticed this giant box at the top of each page that says this inside?
Do not copy/paste old information into new articles without verifying it first.
So yeah. The information about armor/weapon multipliers is out of date, unverified, and in some spots
known to be wrong in the new version, regardless of what Toady said in that one quote (which, I might add, is in the article itself now, which would have been a better idea). That, and that's only a small percentage of the unverified info you blindly copy-pasted in.
And the primary reason for it being deleted was in fact "Duplicate Information" and not the questionable veracity.
Did you read any of what he said to you? His edit summary was (emphasis mine):
Let's not copy/paste existing articles and pretend they're verified for 0.31, k? There's a link to the thing already.
And his initial comment on your userpage begins with this:
Please don't add information to an article unless you know it's true. We all suspect that a lot of information that was true about 40d is true about 0.31, but for most of it we don't know. So for information that might be true, look at the 40d article. For information that you're sure is true, put it in the 0.31 article. From the comments you added, it became clear that most (if not all) of the things you copy/pasted are things you suspect are true.
You responded to this by being really confused over what the verify tag is for (or rather, being your old self and assuming that it's intended for something it isn't), and saying you'd "shut the fuck up" because you're "clearly [...] not wanted". VengefulDonut tried to calm the situation down and explain how the tag is used, and apologized for pissing you off (which wasn't even necessary on his part), and you remained obstinate, apparently going as far as to call him a "jerkoff" for actually understanding how the wiki works and trying to explain it to you.
Quite frankly, this isn't even the first time you've acted like this. There have been other cases of you copying over old content to new pages without verifying, or cross-linking 2010 namespace articles to 40d articles (although I'm not sure of policy on that), and do you remember that time months ago when you were making really angry comments (on the wiki and forums, I believe) about how there's no way to watch a page, without bothering to ask anyone or find out? You honestly come off as extremely presumptuous and as if you'd rather whine and complain about things you don't understand before even making an attempt to understand them.
The fact that you're bitching out and insulting wiki moderators/contributors on the forum for correcting your mistakes (and for apologizing after getting bitched out by you) is pretty telling.
