I've playing Shadowstriker for a long time, and yes, they are spending too much soul and mana, it's a very "expensive" class, because you have to buy some crystals and it's not cheap. The spells are not doing a good damage, especially the Shadow Dagger Throw (don't remember the name), doing a very low damage and costing too much soul. For me, Shadowstrikers were very nerfed. Compared to a Berserker that spells are doing much more damage, they don't spend soul and their hunting spells are doing a better damage for a low mana cost.
