I'll Miss Old Poppy
I never fail as her. She is too good. I have armor pen reds, armor yellows and 30 percent CDR @LVL 18 FRO MASTERIES AND BLUES/QUINTS.
build trinity force, Bloodthirster, Berserker's Greaves, two Phantom Dancers, and a Youmuu's Ghostblade.
Take smite with you top lane just to survive farm phase. Proceed to pull ahead at mid to end game, and take each person out In a second each.
I highly doubt new poppy will have the same level of end game with a full damage build. I hope you can preserve her power.
