Why is casual mode any worse than what everyone I know did instead: just restart the map? While I get that having to go through the map flawlessly or permanently lose a character you were attached to was a thing about Fire Emblem, I know very few people who actually followed through with the permanent death and instead chose to restart the map and lose nothing but time. The difference between casual mode and normal mode is how much time a player spends on the map.
Yeah, having an option to replay an older map or the ability to restart the map if something goes wrong are pretty good arguments against having a casual mode. Though if you think about it, casual mode is just cutting out the middle man of that equation: instead of having to reload the map, the player just toughs it out and moves on to the next mission. Reloading the map repeatedly is just a more time sink heavy version of casual, albeit the person is likely to complete the battle with a stronger comprehension of the required strategies than someone who just winged it once.
