I think they are on her recommend list is why people do that.
I'm laughing at all the idiots that think building AD is within her support budget right now before preseason. There's a reason Pyke is the only AD champ played as support. He's snowball reliant and has a massive gold funneling tool.
Building supportive is literally the best option because you have the budget for it, you'll have the extra utility, AND extra damage.
If you itemize for damage...her ratios are terrible...and you have relatively low utility, mobility, burst, and DPS. What exactly do you gain again for going damage? You're never going to win unless you end up so far ahead that it doesn't matter what you waste your gold on. FFS she basically self-stuns with autos/Qs. If you aren't at least taking Hail of Blades to prevent that, you're even worse at the job you're implying you want to do.
If I wanted to build for 1.2 AD auto attacks with some utility, I'd just play Ashe and not suffer any of her drawbacks.
