Ninja Tabi should have its passive changed to apply to only champion basic attacks
I've never thought Ninja Tabi was overpowered in a teamfight or a 1v1 duel, but rather the fact that you could basically permafreeze the lane under your turret and any skill required to manage waves is basically thrown out the window with this item. It's especially bad when the enemy laner gets a kill, and buys this item, meaning not only is it unlikely you'll ever kill them even in your minion wave, you can't even stay in 500 range of CS or you'll die from a gank because the wave is under their tower permanently. Personally would rather have this nerf over the current -10 armor nerf.
