If time is going to go into fixing Living Shadow, it needs to go into reducing the animation lock that you waste both summoning it and waiting for it to actually start performing actions. It also sounds like this "big" 120 second cooldown ability only does 40% of the damage that you would have done using those abilities, despite performing AoE moves in single target. This is a whole new layer of clunk on a flaming mess.

I'll leave you with this: even your shadow has a better Darkside aura than you.
