They aren't nerfing blink. They're nerfing shotguns. The much reviled "long range" shotguns start suffering significant damage fall off at about 15 yards. They have an effective range slightly larger than the diameter of a titan's bubble. Any significant nerf means that merely using your jump power places you out of effective range. Should Angel of Light be absolute protection from shotguns? Because that's more or less what you're arguing for. Further, shotguns are not just used in PvP. We use them quite a bit in PvE. Have you played with the shielded teleporting captain ultras in PoE? They can eat a full magazine of shotgun to the face and still be trying to decapitate you. Which they can do with a single hit. Go visit them a bit and then tell me that shotguns need a nerf.
