ive just tested this. If I donate a gunner, my donation given stats increase by 1. If I donate a juggernaut, my donation given stats increase by 1. That's very bad. It does not reflect the cost of my donations. The juggernaut takes up 3 slots; the gunner only 1. I am requesting and receiving gunner donations but giving juggs. The stats make me look like a leech! Will carefully consider any future donations of anything 2 slots or more... WDs, priestesses, brutes, heavy gunners...
