I don't like Phantom Dancer from a design standpoint

I thought the point of making sure no Critical Chance item is directly tied to defensive stats was so that Critical Chance building carries don't get tanky stats, yet here's Phantom Dancer, a Critical Chance item with a passive defensive steroid. I just don't see good justification for this.

1. Crit carries are primarily DPS by nature, so their primary defense should be being Bursted down by raw damage. Defensive stats negates this as a fundamental weakness, which makes no sense. Maybe this could be justified if, for its defensive steroid, ADCs are also doing significantly less possible DPS by building this item, except

2. Phantom Dancer grants the highest Attack Speed of the Zeal items, and therefore is the best DPS option as well (sans triple hitting off of Runaan's). This seemingly turning into the best ADC item doesn't even make sense when you consider that

3. Phantom Dancer doesn't even represent an ADC play style or gimmick. ADCs poke from range , they are responsible for wave clear , they need to flexibly team fight and DPS , but they don't Tank through damage . Maybe you can make a case that the Melee Crit carries do need that sort of tool, but that would at best turn the argument into "Make Phantom Dancer a Melee only item".

I've put a few thoughts together

1. Make Lament a stacking passive: This is the smallest change you can make to Phantom Dancer that could still make it do its current job, but also make it make more mechanical sense. If, instead of instantly applying a 12% Damage reduction, but instead a 3% Damage Reduction that stacks to 15% as you keep auto attacking a target, you are still playing by DPS champion rules. It still irks me that a Crit carry could potentially get free defensive steroids, but at the very least, you would still have the weakness of a normal ADC by having time commitments and being blasted before your damage can ramp.

2. Nerf Phantom Dancer a lot: The least creative answer, and in my opinion the least fun.

3. Rework Lament: You know what the Zeal item archetype doesn't have? Emphasis on ADCs kiting. Maybe, dancing around their enemies? Give Phantom Dancer a passive similar to Furor, where every time you hit somebody, you get a move speed bonus. Maybe it's only active if your target is within a certain range of you, maybe it stacks, maybe it's a massive move speed bonus that rapidly decays until you attack again. Just something that emphasizes proper orb walking and kiting.

What do you guys think about Phantom Dancer?

EDIT: Well apparently you guys really like thinking you're a lone carry as ADCs. I'll keep that in mind. Removed a single phrase that doesn't change the content of the rest of the post.
