Particle Systems - attached to objects behave differently?

I have a particle system setup looking great when I just drag it into my world.

However when I add a particle system component to one of my objects, and duplicate the particle system settings exactly, it seems to behave totally differently. What are some likely causes of this? Are the size parameters relative to the object they are attached to? It seems like more than that. How do I set the rotation of the particle system relative to the object? With a script?

Well my solution for now was not to attached it to the object, but to instantiate it directly on top with a script, rotate it the way I want with the script, and good to go.

Seems like the editor needs a system rotation section.
