For the Jedi Shadows the students will have to be introduced to dark side powers. While they will not be trained in using them. They need the familiarization in order to prevail in combat. Shadows understand both the Dark and Light, however stay inherently loyal to order through peace, And like Guardians, they are extremely skilled in the blade in fact moreso. If you look at Anakin Skywalker and Obi-Wan Kenobi, Anakin was the more skilled swordsman, he took an unconventional path with his fighting that was an upgrade to how Obi-Wan fought. Obi-Wan was just the more experienced, and didn't get cocky about being strong.
They also have the force mastery of a Consular. While not as strong as Yoda, they would be able to last in a force match against some Sith Lords with ease.
Jedi Shadows if successfully trained (some cannot handle the rigor and fall to the dark side) have an extremely high resistance to the dark side and are near immune to mental alteration.
