You changed the build :O Nice guide though broski but now since its a real guide Ill give some real feedback. AP/attackspeed? Im not really sure if thats viable considering the low base damage of her auto attacks. In cougar form too she dosent benefit from attackspeed. While it does benefit the guinsoo's I think I'd drop the Nashor's because it dosent really benefit Nidalee's abilities. It would be better to go flat AP. If you really did want to go hybrid (which I think is the best route in the new meta) keep nashor's but drop rabadon's for trinity force and atma's impaler and drop the rylai's for a warmong's armor or frozen mallet. This would give the best of both worlds considering her abilities scale off both AD/AP and you'd actually have some decent health and attackspeed. Sheen would also give a great boost to your DPS. As for you starting item Doran's is a strong pick but not really because she is mana starved. If need be she can always switch forms and wait for regen. Be more specific and say you need to keep up your spear harass and heal. Make these changes for optimal DPS/Health and you should be supporting/offtanking like a boss. Runes are strong for an AP carry - mention survivability is not a huge issue early if you have enough mana to heal. Otherwise good guide, good choice of boots, good summoner spells, good tricks and tips - GREAT GUIDE A:LKGJDLS:KGJS:LDKGJLS:DKGJDS:GKj. +1

just something i sort of disagree regarding the use of heal. You should be healing you carries first then your tank. The carry is more squishy and needs to stay alive as long as possible to maximise your team's damage output. Not to mention the attack speed buff on the heall will help them deal out even more damage.

Otherwise a good guide. I also like the fact you explained how leveling her skills does not affect her cougar skills.
