My Personal Guide to Fixing Nidalee
TL;DR - Just make
an energy based champion so she can't spam spears everytime it's off CD when late game comes around.
Since I think that energy would castrate her spear-spam, which while fun is unhealthy, I'd say give her Q hitbox a tad buff so she doesn't have to have pin-point accuracy or luck to hit them. Considering that the time in between spears would become reasonable I think it's equally reasonable to ask as much.
(This would open up a slot for another 120 AP item since she wouldn't have to build mana regen. Gah! I'm already thinking of the possibilities this could bring for Nid builds :D)
Anyone have a better idea that doesn't completely gut her fun-to-play kit or completely remove her from the meta?
