actually it should be built every game on some of the champions listed in 'good', like Katarina, Kennen, Fiddlesticks, Lissandra, AP Nunu, Swain and AP Amumu
Xerath and Ziggs have CC that's either delayed or ranged based, and will always die once the active is over, unlike say Brand who has ult to constantly do damage while he's in stasis, and has Q. Zhonya's is a pretty crappy item on them.
In fact I should probably move Nidalee to that section but she has a small dash.
Meanwhile: Maw and Mercurial can always be built, Edge of Night if they don't have low CD poke. Very few games have only physical or only magic damage, so there should always be defensive items for either side (there should be an ADC item that reduces ability damage tbh for enemy AD assassins)
