Senna's "spooks"/"souls"

Tried out the champ in the practice tool and she feels very smooth - but I think will require a bit of post-release balancing. But kudos to the devs for trying out an innovative marksman/support like this. My only criticism at this point is that the spooks/ghouls/spirits are a bit hard to see on the default skin. Thresh's souls have a bit more of a glow about them. Perhaps this problem is fixed with the fancy "True Damage" skin, but it seems strange that the souls on the default skin are so tricky to pick out amongst the minions (not to mention, disappear so quickly).
