Inara's weapon is accurate and the projectiles are fast but it fires its burst slowly and has very noticeable falloff at mid range. Erratic movement and keeping your distance will reduce her output effectively.
Inara's Impasse has very high health and can be annoying to take down, especially without Bulldozer. If the enemy Inara happens to use it near the payload, remember that if the payload touches it it will instantly be destroyed.
Inara's CC immunity skill can help her nullify effects such as Tyra's aoe fire, Willo's Dead Zone and Jenos' Void Grip. It can be used during the effect as an immediate cleanse.
If the enemy Inara is using the Tremors legendary then focusing on destroying her walls when she creates them will significantly decrease its effectiveness. Use the anti deployables item and not anti shield since she deploys a wall not a shield.
