Speed is probably the worst to have at a bane so it might be hard to salvage her, but you could ponder running darting stance to maybe save her speed or just run speed +3 and iotes shield.
Her 30 speed mixed with Fury's +3 and Hone Flier's +6, she'll be at 39 speed. If you have a Camilla's refined axe, then that's another +3 to speed when near her, allowing for 42 speed. Goad Fliers for another, what, 4 speed?
