More non sense coming from someone who has noever been in a production role.
The agent is letting her know in advance what she will and will not work with.
If you are looking for an agent who is an expert in this area you are going to have to go elsewhere.
Seems to me this agent knows her strengths adn weaknewses and she probably is letting you know from previous experienced where people have been happy and where people ahve been disappointed.
