I buy this item pretty much all the time and have since it was released and I approve a price increase for it. I will have to think more about who I will pick it up on now its not a must get first item anymore.
It really isn't that bad of a nerf. It's a slight nerf to supports because you can't get 4 wards like you can now with flask start. For everyone else though you can still start flask/ward/2 pots which should be more than enough sustain.
