Corsair and Slayers in Rivers Rest have been absolutely excellent for me. I have become pretty wealthy it feels like - and it nice I have had zero problems picking their boxes. I am a TWC ambusher and I have always legged them first and then come back for their heads just because they have a lot of blood and I basically have completely avoided any damage. I don't think I have died from them since I was level 31. I will say though, I am almost always full dreavened. Water Walking is an absolute must.
