tbh I decided to play her when her rework was announced and got multiple Quadra kills across multiple games with multiple, highly contrasting builds. I don't know why she's being changed so much. Usually Riot keeps champion kits fairly in tact unless they're a low mobility champion like pre-rework Sion that had a lot of tools but no way to effectively use them. Current Poppy has a MS Increase on W AND a Dash on E.
Poppy probably needed a new Passive and Ultimate. Q Auto, E Charge and to a lesser degree W were iconic parts of Poppy's kit, as was the tunnel-vision element of Poppy's Ultimate.
When her rework goes to live, Riot may as well change her name to 'Generic Juggernaut #3'.
All I expected from this rework was a new model with cleaner animations & interactions, new Passive, new Ultimate and then tweaks to Q (keep it an AA reset), W (keep it a Rageblade-type ability that stacks up in combat) and E (keep it a dash with a stun on terrain). Maybe change what those abilities do, but keep their function the same.
