Well, in addition to the nine characters you already mentioned, I'd say Ymir (because I feel that she was used well, and I don't think anyone will disagree that her character was a strong one while it lasted), Floch, Marlowe, Kenny, Hannes, Keith, Magath, Falco, Gabi (whether you like her or not doesn't affect whether she is well-written), Sannes, Flegel, Nick, and Grisha.

Just because you feel that Sasha never got her do does not change the fact that AoT has many well-rounded characters.
