I know she has been tuned more towards a support, but I never felt morgana lacked any damage as an AP mid laner. I remember going into a game as AP Mid Morg with ADC masteries, and snowballing into a 4-and-0 aganist a Zed with zhonya and Rod of Ages. She still has insane base damages as well as really strong ratios: she can easily delete squishy carries with a snare > puddle > full ult channel combo (Tormented Soil hurts buckets if you are stuck standing on it for the full duration).

The major downside to AP Morg over other mid laners is the insanely long cooldowns her abilities has - you're looking at 10 to 13 seconds of waiting between her abilies. Also her spell vamp passive is somewhat lack luster (especially when she has only one single target damage ability).
