I don't think they've weakened, especially since the Devil Kings seemed easier to replace. After all while God's death got covered up, their deaths were made public.

If the blur's done anything, it's more around the lines of Kiba's balance breaker, as well as the fact Xenovia can even still wield Durandal despite she's a Devil.

I think the problem is honestly we've never really had any named Angels as antagonists. We've had a Devil antagonist and a Fallen Angel Antagonist, but never has their been one for Angels despite we know some sided with the Khaos Brigade.
