Well now poppy is dead and boring.....
Sorry to sound harsh, but she will be another sion. Oh, everyone praises him for a wonderful rework, but people don't actually play him so....
Poppy was one of the wonderful champs that had viability with nearly every build - Pros have successfully built her full ad, full ap, bruiser, full tank, hybrid, you name it. Most importantly her playstyle was UNIQUE!!!!! I know her ult was problematic, but lets get real, that was an easy fix. Remove it from full immunity to a general damage reduction and balance - it doesn't get simpler than that.
instead Poppy is being reworked into a standard bruiser/tank, pigeon holed into a "build tanky or die trying" build. If she does it well, she will get nerfed, if she does it poorly, she simply wont be played.
The ONLY moderately interesting thing about her will be her ult, which is gimmicky and will stop being fun as soon as players have used it a few times.
Riot, I'm sorry, but you have gone through and murdered every champion who had any kind of build diversity. Don't tell me you are all about decision making when every champion that actually has decisions is reworked and destroyed.
AP gp - dead AP yi - dead Top/mid soraka - Dead Jg Ali - Dead
On and on i can go. Instead of taking the time to balance properly, you just remove anything that doubles your balance work. I suppose that is the easiest thing to do, but it sure makes for a boring experience when you know EXACTLY where every champ is going and EXACTLY what every champ will build.
edit: Go ahead and tell me im wrong and downvote me. The proof is in the pudding. lets see if you guys are actually playing her in 3 months. I GUARANTEE you wont be.

rework was "bullshit" and hyper nerfed
Just like some didnt liked sion rework or rengar rework
Its almost always the communitys fault why reworks are either to weak or to strong(
