I really, really hope it doesn't, but with the right build, you can keep Shadow Form up indefinitely with 8 seconds to recast it. This means you can:
-Farm Raptors stupidly easily (basically 1-2-3-4-5 and win)
-Run anywhere with no chance of failure. I just ran from Beacon's To Droks without knowing the route and having never done the run before (only watched others). It was very, very easy, and the lowest my health reached was 400, from the AoE damage of giant stomp. I took "I am unstoppable" because it prevents knockdowns, and, well, it's true!
Although it's imba, I've actually never had so much fun. I've been exploring tyria and building up my cartography title completely solo without dying once, and I love stopping for the scenery. I can imagine SF being used in UW to replace the Obs tank, along with a 0% chance of failure.
