Personally, I have no problems with my affinity, even if I don't see how August can be dark...
I would like IS/someone developed a new way to discover it. Next personal project perhaps
Well, I thought of modifying and adding supports:
Support 1: FE10!Jill (Thunder); 50+5
Obvious reason for this one, and we earn a critical, critical evasion and avoid (cool huh?)
Support 2: Mareeta (and I'm giving a best guess, for she has no affinity if I recall well, Fire); 15+5
Support 3: Roy (Fire); 25+3
Support 4: Fir (Fire); 10+3
Support 5: Sigrun (Water);0+5
Support 6: Leaf (since Earth is the nearet one); 30+3
Support 7: Lance (Anima); 0+3
Support 8: Katarina (guessing she's Dark possibly); 10+5
