Damage on the two bosses seemed about equal, but I've only fought the LAC once and not a serious attempt.

Now lists the lvl35 Skadi feet as a drop from Dekka. Has anyone seen it drop this? It just seems odd to me that they would make the lvl35 piece a rare drop from a NM whose common drop is the same lvl15 piece. All that's going to lead to is people throwing away lots of the common drop because you'll always have an excess no matter what you do.
