Just a short personal list, YMMV of course
Most of the instant travel magic (overland flight, teleport etc) because they such away travel which is part of the danger and fun
Any of the various Raise and Resurrect spells because the revolving door is silly
Continual Light (and the others like it) except as an enchantment or as part of a high level spell because it ruins game worlds.
The Return of Planescape? - Curious. There is a brief note on this 'countdown' at Enworld.
