>What are they doing with their characters?
Simple:
In TAWOG, potential of a given character is irrelevant. The only thing that matters is how well they bounce off of Gumball and - even more importantly - if the writers actually WANT to elevate such a character by creating a special bond with a spastic blue cat. That's why the only students that matter are Penny, Carrie, Sarah, Rob and Hot Dog Guy.
