Simple and direct Zoe question

Way back in the days when dinosaurs walked the earth and Summoner's Rift looked like a neon version of World of Warcraft (patch 4.10), as part of a GU had her Q, spear toss, reworked (read: nerfed hard) with the following note:

With her oppressively high spear damage and catlike (maybe just cat-ish) elusiveness, Nidalee's been a contentious low-risk, low-interaction champion for quite some time. Specifically, old Nidalee's gameplay often revolved around the question of "when should I stop throwing spears?" to which the answer was typically "never."

To that end, our goals with this Nidalee gameplay update are to tone down some of her many frustration points while also giving her more options other than chucking projectiles. We also saw this as a great opportunity to cement Nidalee as a real shapeshifting huntress, which meant stronger ties from her human form to her cougar form. Additionally, by connecting Nidalee's offense with cougar form, she now has to balance her high escape potential against her ability to hunt down squishy targets ("Leap away or leap at their face?"). There's certainly more counterplay (and teamplay for those playing around Nidalee engages) when a cougar goes flying into the backline versus a single nuclear-tipped spear.

Let's do a quick find and replace on that first paragraph:

With her oppressively high star damage and childlike (maybe just child-ish) elusiveness, Zoe's been a contentious low-risk, low-interaction champion for quite some time. Specifically, Zoe's gameplay often revolved around the question of "when should I stop throwing paddle stars?" to which the answer was typically "never."

My question is thus:

#How do those concerns about Q not describe Q to a tee, and why does the same reasoning not apply to her?
