I have been using my vengeful echo build with me Mesmer/Ritualist in the Wajjun Bazaar for some time, farming Jade Brotherhood and Am Fah. I know there are better places to farm but...I have my reasons

The build I currently run with is:
Channeling
Arcane Echo
Vengeful was Khanhei {E}
Mantra of Flame
Vengeful Weapon
Ancestors Visage
Soothing Memories
Sympathetic Visage
The usual vengeful echo build with a minor tweak (Mantra of Flame) so that the Jade Brotherhood Mages deal less damage - plus there's the energy bonus! The Jade Brotherhood Ritualists seem to be able to heal everybody too fast! so ordinarily, if I were facing a group of knights, mages and mesmers I would be able to get them all down with 3 cycles through Vengeful was Khanhei, half of them still have half their health intact if there is a Ritualist around.
I had thought about dualling it with an Ele so that the Ele could spike off the ritualists nice and quick but where's the fun in that when you could potentially solo them?
So does anyone have any ideas on what I could do to get rid of the rits? I can't think of anything anymore...I thought about casting Spirit Shackles on them to drain off their energy so they can't cast anything but the problem is they use Tranquil was Tanasen so they don't wand me at all...also I can't interrupt him because of his ashes...so I'm stumped.
The main reason for wanting to be able to solo them is to be able to solo the whole island to make the run a bit more worthwhile (plus I might get one of their lovely little fans!).
