Astarion feels like a College of Lore bard to me because he’s so well-spoken, witty, and dramatic. He feels like somebody who would talk trash and sling insults across the battle field (via Cutting Words), his snark the last thing his enemies would hear.
As we find out later in his story, he’s also needed to be charming and charismatic to carry out his… master’s wishes, which is also bard-like.
