This gave the others enough time to destroy the Titan.
Keep your barrier up when you're in her line of sight, and Shield Bash to get away quickly.
You can increase the knockback from Shield Bash by activating Whip Shot immediately and sending the target off of a cliff or the objective.
Whenever she damages an enemy with Rocket Flail or Whip Shot, a healing aura will be created around her which heals allies over time.
