Far too overpowered. Her passive already is too much; it essentially allows her to be a support with no cs but still completely remove an enemy duo lane's viability. Think of it this way: Say, in a normal game, your carry has 250 CS and a normal support has 0 CS. You have suddenly changed this to 250+0 v 250+0 to 250 + 25 v 225 + 0, a free 50 CS boost. This does not count kills either. She would destroy snowball champions as a support. Her Q is, in my opinion, the most balanced of all the skills, depending on its range. Given a short enough range, it allows her to be interrupted, creating reasonable counters. Her W and E also seems overpowered, in my opinion. A Q+W+E basically lets her and a lane partner harass extremely effectively with little chance for retribution and also allows for awesome ganks or tower dives. No current champion has permanent stealth; it would be far too strong. Furthermore, her inbuilt gold steal aura synergizes incredibly well with this. This also partially negates Q's main downside, a very long channel time; how can you interrupt a champion who is not visible? Her ultimate, I feel, is extremely powerful as well, but I don't see it fitting in too well with her role and her kit in teamfights. Of course, she does have the option of using E to break away, especially relevant in a duo lane situation where she channels a Q, throws a W, dashes in with a R, then runs out with her lane partner with an E.  This also makes her especially resistant to ganks; she already has the brush reveal and escape, but what would she do if Rammus is barreling in double buffed? No matter, dash in, steal his buffs, then turn around and kill the ganker with your buffs.

Another, easier way to look at it is like this: She has a shield, a slow, an ally speed boost, two free ghosts, a permanent speed boost passive, a reveal, a cooldown lowering, free tenacity, an ally QSS, a long range dash, and the ability to steal buffs. Q and W also work extremely well in teamfights.

I think you have some good concepts - the cooldown lowering, the buff stealing, and the long channel as a balance - but it ended up making your champion far too strong.
