Full tank Poppy one shotting....

So Poppy is a very tanky champion, specially with her passive making it to kill her very difficult. Tanky champions are a good part of League but I don't think a full tank poppy who's very difficult to take down should be one shotting other (squishy) champions. Idk where in the world the damage exactly comes from but Poppy does SO much damage for being SO tanky and honestly it isn't healthy for the game.
