Maxperson
Morkus from Orkus
You didn't retain the ability to speak. It changed with the form and badgers can't talk. They don't have character classes, either. Basically, you were a badger who remembered his former life, but not the abilities of class."Alternately, the idea of talking animals might be too ludicrous for one's serious fantasy TTRPG.
"The person reincarnated will recall the majority of his or her former life and form, but the class they have, if any, in their new incarnation might be different indeed. Abilities and speech are likewise often changed."
Basically, you had to hope that the new form could be the class you were, demi-humans sometimes could not be, and pray that the new form was even humanoid of some sort, because it sucked to just be an animal with your old memories.
