Randuin's and Frozen Heart's stacked slows are pretty useful against autoattacking team and I would recommend those over Sunfire in that situation. Against a balanced team, I normally prefer Sunfire + Randuins to deal with physical damage unless CDR is a huge priority since Frozen Heart adds no health.
