I still don't see why this champion reminds everyone of Riven... I don't see any similarities myself...

And the difference with Fiora is that Elyra's ult is actually just a buff, and not a spell you cast. You also don't get untargetable with it. (and, in contrast to Fiora, you're also not MEANT to be untargetable with it)
