Playing against Gwen

How to counter and exploit weaknesses

1

Her W doesn't protect her from attacks inside the zone: step into her mist to fight her.

2

Gwen is weak in early game (levels 1-4) — punish her before she gets her stacks and first item.

3

Grievous Wounds reduces her Q sustain (true damage + heal), which is her main survivability.

4

She's better in 1v1s and split pushing — force teamfights where she's less effective.
