Tip overview

Willo is heavily countered by mid-long range fast projectile and hitscan champions. As Willo in this situation, play carefully by denying line-of-sight of those champions and if you want to trade dmg with them peekshot from cover.

Willo's Dead Zone ability is very effective against 'local healing' this includes grovers healing, Grohk's totem and similar things. Dead zone will prevent deployables from being effective and will force champions like Grover to move out of the zone.

Do not underestimate the effectiveness of getting really close to them and flying straight up, flickshotting Blastflower down onto their heads. Try to use this against Flankers with exhausted mobility and other Damage champions.
