I focus on Righteous Fury to start with because it enables you to bring down enemies quick early game so that you can get your build rolling quickly. I focus secondly on the heal because it helps you survive and keep teammates up, also getting you more kills and making you a versatile supportive teammate while still thrashing on your opponent.

I use flash and exhaust to help me either flash to an enemy and bring them down if they are running, or the exhaust/flash to get away from a pursuer.

This build can be very devastating if played well early game... However, if you get behind either by dying or a feeding teammate, the build can be squishy, especially in a group fight. Her ability to fight from the sidelines is an edge still. She just needs the build to move quickly or it can be tough late game.
