@Meddler How do you justify Nidalee's cougar forms' resourceless...ness?
How do you justify Nidalee's Cougar form having no resource?
Even if you can justify it (love to see somebody try) it has a** glaring clarity issue**: Her mana bar still shows while in cougar form, but it is no indication for her power level. She can still jump away or even kill you without mana.
When you see an empty mana bar, you generally think that enemy cant use their abilities.
I would suggest at least removing the mana bar (for the enemy players, could stay for the Nidalee player) for clarity's sake. But I would further suggest giving Nidalee's cougar form an energy resource, right now she doesnt need to make any strategic choices around using her cougar form abilities.
