If you like the unit I would build one and fodder the other to a green unit for arena scoring... if you don't like the unit use one for fodder and the other as a ritual sacrifice to IS so you get better pulls in the future, as any sane person would
as for you, i think u should build +res one and keep the other for emergency swift sparrow fodder. AAAAH no, fodder aerobatic instead for Camilla or other flier. it's like a godly flier skill
