Proxy farming denies his Siphoning Strike (Q) stacks at the source, and even when caught by Wither (W), Fling (E) throws him off to widen the growth gap.

He needs to stick to stack Hemorrhage (P), but movement-speed kiting plus Mega Adhesive (W) and Fling (E) keep peeling him off, so he can't reach 5 stacks to empower Noxian Guillotine (R).

With no dash, he's kited endlessly by the movement speed and can't land Haymaker (W) or Facebreaker (E) on a fleeing Singed.

His Decisive Strike (Q) silence only lands if he steps into the Poison Trail (Q), and the constant poison damage keeps him in combat, shutting down even his Perseverance (P) regen.

Even when he closes with Thundering Smash (Q), Fling (E) cuts his engage and throws him under tower to blow up the dive, and on the Poison Trail (Q) he's kited endlessly by the movement speed.

Blinding Dart (Q) and ranged poke kite him, while Noxious Trap (R) mushrooms block his proxy routes and engage paths to shut down any approach.

Sanguine Pool (W) nullifies Fling (E), and ranged Transfusion (Q) poke with lifesteal outpaces the constant poison damage.

Condemn (E) shrugs off Fling (E), and Tumble (Q) mobility with Silver Bolts (W) %-max-health true damage melts a tank Singed from range.

Ranged poke plus Electrical Surge (W) and Lightning Rush (E) mobility kite him, and Mark of the Storm (P) stuns cut his engage to deny any approach.

Mercury Cannon (R) form's ranged poke and Thundering Blow (E) chip his health and shove him away before he can close.
