Help with salvageable IV units

Jeorge, Camilla, Sheena and Julia are the four you should work on, as their IVs are decently good or just not too harmful to their current role.

Summer Corrin +Res/-HP: This could be a good mage duelist...but isn't quite as optimal as +SPD. Do you have Hinoka/Goad Fliers? If so, you could prioritize this but otherwise I'd hold off until you do.

Sheena +Atk/-Hp: This is interesting... You might be able to pull off a Wary Fighter/Brave Axe+ build with these IVs. It's rare to see a Sheena with an offensive presence and she retains most of her bulk. It would allow her to charge her special faster which is always a good thing.

Camilla +Atk/-Hp: This is one of her better IV sets but she really isn't a stellar unit. Her niche is antimage but her default weapon sets her up to get doubled...maybe if you inherited over a different weapon? She'd basically be immune to blue magic with Emerald Axe+.

Jeorge +Spd/-Hp: This brings him up to 35 base speed. That's very respectable. He's still a second tier archer (after B!Lyn and B!Cordelia) but he can do well enough with 32 base attack and his legendary bow.
