I'm finding that her passive ability is amazing for 12-5. Before, the squad that had to clear out the nests before the boss would usually die to it. Now if my Edelweiss squad clears them out, it usually just solos the boss by itself. She even got me a 12-5 full clear with no lost UNITS, because with lucky pathing an Edelweiss squad can run around and solo the whole map. My farming team for the map now is just my main squad and my helper in front, with the rest of my squads slow moving in the back to pick stuff up when someone else reaches the goal.

Also I love one of her moving sprites where she's riding her hammer like a Segway
