Is there a rule for defining complexity?

There is nothing right or wrong here. As a thumb rule, if a drawing has more than 20 dimensions it may be a good part for MIM. MIMO can also make products with simple structure, but what MIMO wants to emphasize is that the more complex the products, the more prominent the advantages of MIM technology.
