Overall the game looks amazing, but it seems at least one glaring flaw has carried over from EWoM after all: technologies that make little sense. It doesn't really help the immersion factor that you have to learn a technology to recruit champions. Also it's wrong, because only players that focus on that technology tree can get them. It should instead be based on the perception that a hero has of the player: if he's powerful enough (be it with a focus on military, or magic, or economy, or whatever) then even a high level hero will be interested in joining.
I was baffled when this kind of technologies were introduced in EWoM and I am every bit as baffled now. It's a pity, so far there had been no evidence of this kind of thing being in FE and I was reasonably certain they were gone for good...
I hope they will be removed in the Beta, since really it's the only thing that seems off to me of all the previews I've seen.
