We did it on Vicious last night, a SS/WP, EM/Bio, Ice/Elec, and me on a Ill/Trap troller.
Bio was the weakest, WP next, and Elec last. As long as I didn't get mezzed I was ok with PA taking the brunt and I'm capped on melee def and all res. Taking the alpha from the Goldbrickers was impossible on any build.
I think with all the -res it would be bad on any AT going that route, of course with the high to hit, def probably isn't any better.
I'm wondering how any of my tanks would have done especially my /Rad with his debuffs/heals.
