Fire Emblem: Path and Dawn on hard with no deaths

[Jumpin]

When I play Fire Emblem, I think probably about ~15-25 of my characters usually die in the course of the game. It doesn't make a difference, you get better characters to replace them later anyway.

I consider myself extremely good at strategy games, I cannot fathom how people can manage to get through any of the games without losing anyone; that seems highly improbable. There's always going to be some sort of critical hit surprises. I suppose you could reset levels that you lose characters on, but that is where the game becomes a chore and not worth playing anymore.
