Expys aren't anything new.
What's more troubling is the similar designs. FE6 did the same thing with Marcus (Compared to Jagen), Miledy (Compared to Minerva)...FE6 lifted a lot from FE1.
But FE6 was the first post-Kaga game, not to mention FE1 was a whole five games prior. 1-5 had similarities, make no mistake, but the real archetyping didn't really start until FE6. Still, there was enough to discern differences.
IMO, it's too soon to reference Awakening to that extent. I'm indifferent otherwise though. They are what they are.
