Inara can hide her Warden's field behind the wall (I do this often too with her). This can surprise you and get you in trouble especially if she's using the cripple card. She will take the wall down and you stay crippled exposed to enemy team.
Unless you're a frontliner, keep your distance from Inara, especially if she appears to be coming after you. While Inara's DPS is relatively low, she can use her abilities to trap you close to her and force you to take her damage.
