Great Guide! I've been playing my shade for quite some time(he's level 41 and by far my fav hero), and I've read Plasma's guide often but just discovered yours. I agree with the posters about Neb Form and Grav Emanation, I use both a lot. I don't yet have Inky, but based on your post, I will probably get it. Otherwise my power choices and play style seems a lot like yours. I have Orbiting Death just cause it looks so cool standing outside mission doors, tho I never fight with it.
One suggestion on slotting. I noticed that all your early powers just have the one default slot in them. I personally put all the slots before Nova into Starless Step. Two endredux and three range enhancements make teleporting an awesome travel power.
