I agree that she needed a nerf, I'm not here to state otherwise or argue that she isn't in fact all that strong.
I just think that the nerf to her ultimate should have been made in a different way.
In case you guys don't know, AD Poppy is actually a lot of fun to play. And it's really annoying to see an off build getting gutted by nerfs that are intended to hit her main build, aka tank.
I think a better approach would have been to just flat out lower the base damage, but buff the bonus AD multiplier.
This way AD Poppy can still fastcombo her enemies, and doesn't have to wait for her ultimate to charge up and potentially not finish them off but shoot them away.
I love playing fun off builds, and it saddens me every time one of them gets nerfed. I think league is a better game if champions can be played in multiple ways, instead of just having that one way they work in. It keeps the game fresh and entertaining.
