I like the map itself but we already saw it once so eh
And yeah the DLC's seem to have more "plop down guys and have them fight each other" chapters than chapters with semblances of things actually happening XP
but there ARE some talk conversations here and there... Gaius and Zihark have one in SB2 I believe, they talk about the myrmidon archetype and how Zihark's personality isn't totally like that XDDD it seems to break the 4th-wall just a little

The Bride class is definitely awesome (and lol that screenshot is hilarious XD), but I can also see why people don't like it for Eirika--she only ever used swords yet Brides can't use swords at all... and it seems to have made her much more bratty, whiny, naive, etc., personally I don't really mind too much
As for characterization, again, I'm not one to be so nitpicky or be like "oh noez it's not true to the original", it's not only harder in localizations to maintain similar characterization because it's more likely you'll have new translators that aren't familiar with older characters because other translators worked on it (i.e. even if Treehouse did both FE7 and FE13, it doesn't mean the same people did it), and more importantly it's much easier and more practical to just throw lines that fit the general character role or archetype, e.g. Zephiel, Nergal, and Ashnard are all similar in that they look down on the enemy, flaunt their strength, etc...
