I'm sure we've all noticed that these bosses typically drop Exceptional/Elite Superior/Socketed items. Is this just a different treasure class then the rest of the bosses?

I guess what I want to know is it viable to run these bosses in hopes of scoring things like a 3os archon, or an eth 6os Cv?

why would you post this in char development?

Er, my bad. I thought I was in D2 general. Move it if you please, but my question still stands
