User blog comment:Andrew.heo1/When to Get a 3rd GP10 Item on a Support?/@comment-3970297-20120815122051

For me, I see it as, depending on the support champion and how aggressive you play or what kind of support play you chose to do determines if you want Kage's or a HoG. Philospher's Stone is a basic which all supports get since the item itself is very good, and moves into really good items.
