Double bladed weapons

This type of weapon should be used by Juggernauts and Guardians, not by Assassins and Shadows!

Fully disagree. Guardian and Juggernaut take their inspiration from Anakin, Obi-Wan, Darth Vader, Tulak Hord. All fighting with single sabers. They are more about slow powerful strikes than quick strikes like a Marauder for instance. 

Assassins and Shadows have less examples in the movies, but Darth Maul would be the prime example. Hence, double bladed. 

Of course characters from movies, novels and comics don't follow classes, but this are some of the characters the classes take inspiration from I'd say. And Juggernauts/Guardians should obviously have single sabers in this case.
