Permasin farming?

Well.. I haven't played GW for quite some time, and I just came back to check how things are going. I keep seeing bits and pieces of info on various forums post about this build. Apparently someone figured out how to maintain shadowform indefinitely and farm just about any area in the game.

I find that hard to believe. And even if this was so, it would have been nerfed by now. I did a search but cant find anything relevant.

Can anyone tell me if the build actually exists? Does it still work? Can you link me to relevant threads? Thanx a lot.

It has been nerfed but can still be used effectively to farm
