As a long time Haley 1 player I can understand why they nerfed the -2 spd aspect of the spell. It was really hard against melee heavy armies, especially slow ones. As I read through the fiction (it makes the enemy attacks easier to avoid) wouldn't it be simple to get rid of the -2 spd and just make it a -2 to attack for enemy units within Haley's control range? This would make her less vulnerable to melee assassinations and give more reason for her to be aggressive and support melee units like Storm knights. Anyway just a thought.
