Dood.
6/5 rating filter is very special enough already. No need to exaggerate things. Highlighting DC resources even more is unnecessary (imo). Resources which are included in DC category already have their eternal glory, there is no end to their awesomeness. Anyone who clicked "Director's Cut" category should be already prepared to meet some of the most bad-ass resources of all-time there is in Warcraft 3 universe (even tho this is not exactly true, meh at least mostly). So, no I disagree.
But I suggest giving award (icon) to the resource's author won't be a bad idea.
EDIT: if you are afraid that people (new comers) won't notice there is DC category in THW, I think you don't need to. When I came here for the first time, one of the earliest things I did was checking the DC category in every section . I think most of people did the same, bcs it's not hardly noticeable.
