Here's the squad I used her on. Was useful all campaign and was even the squad I used to beat the penultimate boss (main character spin to win squad handled final boss). Nothing broken or overpowered, just an insanely tanky squad that spams counter and follow up attacks and doesn't die. Could this better? Yes, and whenever I revisit the game I'll change things up. I didn't look up any builds, but just adjusted based on how my squads did. But I found her strong all game.
My playstyle was tactical difficulty, no item abuse.
