I agree entirely with ???, but like OP I was still pretty impressed with the music the trailer had and I really hope there's more like it in the actual game. I am in complete hype mode.

I'm only arguing that Donnel isn't the worst unit, not that he's one of the best. Donny gets Sol, Counter, and Armsthrift to hold his own in battle on top of consistently speedy stat boosts, and he can get his kid Galeforce. That's a lot more than some other units can offer, including Virion. Virion may be "useful" as a father, but he's still outclassed by other fathers in most cases, and to say he's useful for every child is a bit of a stretch. Donny may not have many optimal kid options, but the options he does have end up making fantastic units. The same can't be said for Virion, who can make only a good unit at the very most.

I'm totally cool with children as long as they have a justified existence without the bizarreness of Awakening's writing. Also, the abilities system would have to be changed somehow so that the kids aren't so OP.

While that's entirely true, that wasn't my point.

With a Bronze Sword and minimal grinding?

All the people saying "Donnel" make me sick. He basically solos the entire game the moment you get him to Hero in Hard Classic with a Bronze Sword, which is not very difficult to do if you get him early enough. Also makes a pretty great dad. Virion is probably the worst unit and father, which is a sad shame since he is easily one of the best-written characters in the whole game.
