I know what you mean, but I think the reason why Cedar Fair loves working with B&M so much is because of three reasons:
1. B&M’s are not too intense, making them very re-rideable and GP magnets (the GP makes up almost all of Kings Island’s attendance)
2. B&M’s are always reliable and they can absolutely eat through heavy crowds
3. B&M’s just look so good... when the average guest walks into a park, and they see this towering roller coaster, they are automatically going to assume it is super fun and scary
I think when Cedar Fair approaches B&M to build a new ride, they want them to design it to appeal to the average guests, but I will say that when B&M has the opportunity to make something big... out comes a darn good ride!
