User blog comment:Fistful of Force/AP Nid top vs support/@comment-4593717-20130409142550

In my opinion, Riot's decisions are based on the idea that was too safe while in both human and cougar form. Human form was designed around being high poke, high sustain, and laying traps. Cougar form was designed around being high mobility, high burst, and low sustain. The changes that they have been making have reduced her ability to build the same items as a support that she did as a top, which would make her too strong to be a support. In other words, they emphasized the need for support to build support items, and top  to build AP items. Cougar form was previously a cover all for not dying, simply switching to human for heals, but now it relies on it's mobility to survive, whereas human form uses the heals.

Anyway, that's my spiel on the changes that are being applied to and why they are balanced.
