I tried some time ago to go into FoW and was raped by the mesmer+eles group, using vigorous spirit. Due to this thread I tried again yesterday and after 3 tries, to my surprise, I could kill that group. I was able to kill that group with mesmer 3 out of 4 tries, but it reminds me to coldfires killing, involves some disgusting running aimlessly around.
The group with 1 monk and the 2nd group with 2 beasts and 2 monks r easy, though slow (damn healing signet). To kill the group with mesmer must cast prot, breeze and vigorous and get into their aggro area. U r removed vigorous and recast it again. Then u move stupidly away from them until both eles (if there r more, more u'll have to wait) cast their firestorms. Then u run to mesmer activating SV and IW and start the killing. If eles r able to cast more storms just run away from them. Twice eles were able to cast storm just at the beginning, and the killing was smooth. But once they could cast it again and I had to run a lot. But I was quite happy to see the healing was enough as long as u avoid fire storms.
Then I failed miserably against show rangers and abyssals, they managed to interrupt my prot spirit amazingly often, but I guess that may be avoided (I'll waste a few more entries to check that).
