Spell invulnerability is rare because its impracticle. One spell blocked with a 1.5second duration means you would have to actually see the ability comings towards you like Ashe's Enchanted Cold Arow. That does nothing for the cooldown, or the battle, or just versus auto-attacks.

Most champions have some form of Escape whether its a Dashing/jump ability, traps, shield, heal ability, a crowd control, movement boost. Nocturne's abilities specifically target the enemy.

Shroud of Darkness is the dead leg of Nocturne's abilities and the lack of escape ability is what makes him more of an Assassin rather than a straight up Fighter.
