I'm just going to give it to you straight;
I will be removing Armin from the imagines and preferences.
Now, before you throw your rage upon me,
I do love him, and I know he is a vital character in the Attack on Titan fandom and lots of people love him but my reasoning for this is that I don't exactly like writing Armin and he's not a character I know very well.
I'm sorry for the inconvenience,
