Balanced Units - A minimal balance mod for units

Do you think the Necromancer's upgrade tree is well-balanced? In my opinion, "Grasping Strike" is more effective than "Howl" (first, "Howl" doesn't deal more damage on its own; second, like with the Red Dragon, you need to position yourself correctly to use the ability, and you need to apply the ability before the enemy's next turn – the enemy isn't stupid and will try to move away from the Banshee when they see this setup).
