Poppy isnt buffed correctly
Riot gave poppy some love this patch since she was so forgotten, but they are buffing tank stats on her. Her playstyle was never of a tank, she has always been played as a bruiser but since riot nerfed her based stats she just went to the dumpster. She needs to be a threat in order to be reliable in a game and lasting 2 or 3 more seconds in a teamfight is not gonna matter if she will just be ignored by carries and past by, as well she will just be dps´d even through her buffed shield and such.
