Accents in Veilguard

I've just realized, only Orlesians and Antivans have their own accents in DAV, right? All other places and factions have accents all over the place. I generally think it's fine whether a game decides to assign different accents to different groups, or have accents all mixed up, but why did Veilguard take this inconsistent approach? The Veil Jumpers may come from different places, but aren't Mae and Dorian from the same country, any reason they have different accents, too?

A side note is, Solas also seems to have lost his accent from Inquisition? I’m not upset, just a little confused with the VA direction in this game.
