An early class swap video showed Vake can become a barbarian through use of the change seal.
Did anyone notice the conspicuous lack of soldiers?
Yeah, but its not like soldiers are all that common of a class. It looks like FE9/FE10 may be all we get to see of them. I'm also wondering what the deal with marth is but it is pretty likely that he may have a secret class. He'll probably join pretty late and have a unique class like the final boss(es).
