Nature's Grasp + Entangling RootsFollow

If you have a target rooted, and NG procs on another target, can both be active? Or does the NG replace the roots?

Correct, NG and entangling roots share "space". so one replaces the other if on different targets.

What I find worse (though it makes sense), they share the same diminishing return spot. So if you casted entangling roots on someone next to you and try to get away but your NG is still up (meaning no one hitted you yet) but that charging warrior got near, got rooted and hits you, the roots from NG get a diminishing return meaning lasts a lot shorter.....

If you PvP, Nat Grasp is a MUST....
