ToC non-heroic is a joke that drops whatever the team doesn't need.
I hate ToC heroic myself... I can do it just fine with the team that doesn't need anything from there. (classic pally + 4 shaman)
If I bring in a new character it's usually bad news with several team wipes.
It is supposed to be a fast way to gear up but once I got the weapons on my main team I quit doing it.
