If you are playing Stunning Visage, wait for her shield to come up then stun her, which completely shuts down her shield. Then, she is an easy target to burst down.
Try to use flick shots if engaging Kinessa, as her sniper mode can be detrimental for her. Try to use nether step to get behind her each time she changes direction.
At the start of each round, you can use your first setback at her, sending her way back and having her walk across a big path without any movement ability. If she plays Mother's Grace, act quickly, before she goes into cc immune state.
