User blog comment:Leyrann/Riven Rework - Yes she may be able to use one/@comment-24947613-20150127063155/@comment-24947613-20150127070306

But the whole point of Riven's current "high mobility/zero gap-close" kit is that you have obvious counterplay - being out of her AA range by flashing/positioning/peeling. Giving her gapcloser will completely ruin her playstile. Just imagine - jungle riven, build up ki on gromp with full rotation, then flash initiate from river bush to the middle of the lane with a HUGE shield, into W, and proseed to obliterate with Q,Q,Q. Thats what Rengo, Vi, maybe even Malphite do, not Riven.
