Ok for starters Love the design, have to play to feel out her changes, but... hate the new lore... i realize shes now the "reluctant hero" archetype(or whatever is stated) and not the Hero looking for Redemption or purpose(you can also say revenge, but i never looked at poppy that way), but that's just not as good. The old lore brought a tear to my eye, inspired me to pick up an play the "Little Linebacker"(as my friend dubbed her) but this new lore just kinda makes me feel nothing... i dunno, personally, i think you could of kept the old lore just replaced a few things, and still had the same direction you are trying to go. One other thing this line "Little does she know, she is that hero, and the destiny of Demacia is in her hands." (I realize that can be extremely ambiguous so it's up to us or Riot to figure out where to go with it) ya, hate that line it's too central( more like focused, but meh) for my tastes, it's like the game now has a central hero for demacia, an poppy is it, and that's just... i dunno, not right for a game like this.
TL;DR - like the art, interested in playstyle and VO, not a fan of the lore change.
