Playing against Sett
How to counter and exploit weaknesses
Dodge the center of his W (true damage): sidestep laterally, the cone is predictable.
Don't deal too much damage at once without killing him: he stores the damage for an even stronger W.
Kite him: Sett has no dash (except targeted R) and relies on Q speed to gap-close.
In teamfights, don't group behind your tank: his R slams the tank onto the carries.
