When it comes to AP the necessity of it is very strange for this group of champions.

- The top 3 can fully preform support role without a single piece of AP gear. They all like it, but have high base scalings on their AP abilites plus have plenty of secondary effects in the forms of CC and Shreds/Steroids.

- The middle group is the one that needs the most of it due to the way they support, Karma and Zilean are both very offensive supports, their strength comes from helping your team beat the crap out of the enemy team, and using their abilites to keep allies alive.

- The bottom group is actually exactly like the top group, but with Nid being the odd one out. They can live without having a single point of it, having lots of free stats or plenty of CC.

Nidalee is like Kayle (I think you should add her to the list btw) she is a very flexible champion. AP works on both of them if you're supporting, but it really isn't the best way to build them. They both simply scale better with AD or tanky dps builds.
