The players at my (and other) tables enjoyed it. It was nice to actually see PC have a chance at failing a skill challenge for a change (as opposed to other from other Game Days that were auto-success every time). Besides the 'beaten savagely' result got huge laughs at my group.
My group rolled well, and didn't fail a check in that challenge - and they weren't using the supplementary skills at all. Oh well.
Cheers,
