Not sure if new, but I was waiting around while my group was AFK and cast Avid Boneyard on the ground where we were all standing and got no synergy. So I was thinking maybe one of them was there and hit it, so cast it again and again and again, until none of them could possibly have it available off cooldown. No go. So I go away and cast it; there it is. Move all over the place and cast it, and there it is. Go back and stand in my group and again; doesn't show. They finally start moving so I cast it in that spot, it works in that spot.
