Top or Mid depending on your preference. AP is the way to go atm IMO because it has the most damage in skirmishes, teamfights, and sieges.
Honestly, she isn't really weak at all if you are a god with her (very easy to dodge skill-shots with brush move-speed and cougar W). Her damage, assassination potential, and poke are also huge if you can land those spears. Unfortunately they are much harder to land now after the rework.
But you need to be a god with her to win games, haha. If so you completely dominate. She is Queen of the lane-phase and mid-game and even decent late-game if you can just land those pesky spears (SO SKINNY NOW OMG)
EDIT: Emphasis on needing to be a god. If you can't keep up on farm, can't land spears, and aren't abusing your power in jungle skirmishes, poke, isolated assassinations etc. you won't have a good time. She is really bad for the standard straight-up 5v5 team fighting that a lot of people like to build around in soloQ. If you don't poke before 5v5ing, you will likely lose and be completely useless.
