Instead of stating that the passive root and damage cannot be applied for a set amount of time, i would state that "Entanglment stacks cannot be placed on units rooted by this effect."

This prevents confusion a bit.

Also to prevent game breaking I would suggest that the passives and effects that benefit from bushes be reduced by half, IE Caitlyn gains 2 stacks on every other auto attack from these bushes, Nidalee's movement speed duration is halved after leavign this bush, and rengars' leap has half range.

So this still buffs these champions but it does not make them broken.
