I've played in games that don't allow multiclassing, but never games that don't allow feats. Go figure.
First, this doesn't seem to actually fall into the category of an Appeal to Authority, as it's not dependent on the opinion of some "expert". Jeremy Crawford isn't an "industry expert"—he's the lead designer of WotC for D&D products. WotC does research on what is popular among their customers to help determine what sort of products to produce (so they can maximize their profits). Crawford's job is directly impacted by the data that WotC obtains (in that his job is to design what WotC thinks, based on the research that they do and the data that they collect, will sell).
Yes, he does not describe his data, but is there any question that WotC collects data. So, it comes down to either suggesting that WotC doesn't have the data (which is rather silly), or that the lead designer is misrepresenting the data (and what would be gained from this?).
And you're still assuming the source without evidence.
Majority = More than 50%.You realize, by calling a massively large set of data "sketchy" and refuting it with a massively smaller set of data (8 groups total), you've made a complete farce of what is and isn't considered "sketchy" right? I mean, you have to seen some irony in that, I hope? I know some groups who have only played with Basic rules. Since their personal experience is only with Basic rules, does that mean they should conclude your data is "sketchy" because their personal experience differs?...
Majority = More than 50%.
8 distinct groups, almost entirely independent.
We're saying that I experienced the unlikely situation in each of these 8 groups.
If each group had the normal probability of following the, well, 'norm', you'd expect there to be less than a 0.4% chance (one in 250) chance of my experience. Less than, because they're saying most - more than 50%... If they think there is a 60/40 split, the number drops to 0.0065%....
So, yeah, I'll call the data sketchy.
There is another possibility for those surprised with this information: As large as it is, the Enworld community (at least many members posting in this thread) is an aberration. The great unwashed, unenlighted riff-raff that don’t hang out online with hyper-fans must be legion, and play differently than many here. ;-)
I never played 2e but I've got 35+ years of more-or-less-modified 1e under my belt; along with a whack of 3e. And yes, mechanical build was both way more important and way more emphasized in 3e than in 1e.
"This assertion doesn't match my preconceived notion—therefor, it must be a lie!"
Sounds like US politics.
