Dimi is in an interesting position in that all those who surround him (sans Dedue and Ashe) have Crests but he personally needs the Lions' counsel more than their Crests. Faerghus was likely founded on the basis of their Elite Blood, keep in mind the Empire only have Saint Blood, so Crests and that tradition explicitly holds more value for Dimi.
Compared to Claude, who is surrounded by excellent men and women who explicitly don't bear Crests and for some reason he still thinks Crests are a problem because he's a blind hypocritical retard.
