Nasus has no gap-closer, so he must farm from outside Norra's max-range Memory Spike (Q); constant poke from Beloved Amulets (P) and Memory Spike (Q) disrupts his Siphoning Strike (Q) stacking and loses him the lane.

Ryze has no mobility and short range, so before he can close the gap he is chipped down one-sidedly by Norra's Memory Spike (Q) and Beloved Amulets (P) poke.

Malphite is a melee farmer, so every time he walks up for CS he is exposed to Memory Spike (Q), and he is poked relentlessly in lane until Unstoppable Force (R) comes online.

Before level 5 Kassadin has no mobility, so he is constantly exposed to Norra's long-range Memory Spike (Q) and Beloved Amulets (P) poke, falling far behind in the early lane before he unlocks Riftwalk (R).

Yasuo's Wind Wall (W) blocks Norra's Memory Spike (Q) projectile and even her Beloved Amulets (P) procs, neutralizing her poke; he then dashes in via Sweeping Blade (E) through minions and bursts down the immobile Norra with Steel Tempest (Q).

Zed dodges Norra's Memory Spike (Q) with Living Shadow (W) and Death Mark (R), then sticks to the squishy, immobile Norra and kills her with his burst combo.

Fizz uses the untargetability of Playful / Trickster (E) to shrug off Norra's Memory Spike (Q) skillshot and Journey to Nowhere (W), then closes in and kills the squishy Norra.

Katarina weaves through skillshots with Shunpo (E), Flash, and Bouncing Blade (Q) resets to close in, and the immobile Norra struggles to land Memory Spike (Q), so she gets dived.

Akali evades Norra's Memory Spike (Q) poke with the invisibility of Twilight Shroud (W) and the dashes of Shuriken Flip (E) and Perfect Execution (R), closing in to burst down the squishy Norra with her combo.
