Playing against Poppy

How to counter and exploit weaknesses

1

Do NOT dash when Poppy's W is active: all dashes are cancelled and you get grounded.

2

Avoid fighting near walls: her E only stuns if you're pushed against a wall.

3

Her charged R can be interrupted by CC — stun her during the channel.

4

Champions without dashes are unaffected by her W — that's an advantage against her.
