User blog comment:ClariS/Why Xerath's Passive is Bad/@comment-89.80.9.19-20130319020443

A real passive should fit with the hero, like dealing more damages according to the distance you hit from.

Like when you shoot from max range, you deal some more damages, or gain some sort of bonus (slow? aoe? anything else?) or, why not giving him MORE damages when he's CLOSER to his target, so heroes like Shaco/Rengar, will think twice before going melee with you (just like Ryze), that would be far better than an armor passive...
