I'm wrapping up my second playthrough of the Binding Blade on normal. Unlike the first time, I did this without save states on hardware. The tier list reflects how my run went and isn't meant to be objective.
Here's some other things about my run:

>Recruited all characters
>Banned the arena
>Banned a couple of top tier characters so I would use some lesser used ones
>Could only use the banned characters on their starting chapter and the map where Miledy recruited Zeiss
>Promoted all of the characters that didn't go unused, with the except for Lot and Clarine
>D tier characters were used only once or twice
>F tier characters were used only once but had a significant drawback to using them

Compared to my first run, I thought FE6 was fair but I made a lot of dumb mistakes so I had to restart a lot. Even though there's a lot of bullshit, I actually think the game is overall better than FE7. I think I'm getting close to a A or B rank score but I definitely had to grind a ton of characters. I really want to play hard someday but am certainly taking a break before then.
