Detour EE 8 runs (2 solo)=) 0 boots for me or for any member of groups (did pull an Orb though)
Songs chest EE-ransacked 3 toons, 2 guildies also=1 wizard orb
Full chain 4 seperate times EH=no named items pulled for me (did see 2 khopeshes,1 Gloves,1 bracers,1 caster shadow mail)

Has anyone narrowed an approximate drop rate %? Just curious...gotta get 3 sets of EE boots and go.
