I do think that the names are one of the major problems that students or newcomers have in dealing with complex numbers. When people see the words "complex" and "imaginary" they think "complicated" and "nonsense". Real-world examples (e.g. R-L-C circuits) and visual examples (in both Cartesian and polar coordinates) can be really helpful.
