Defeat 5 enemies with Jawa Engineer feat

Agree this is pathetic. 

That said, since JE is light side, you can run him under Jedi Master Luke and use his granted ability on JE. That granted ability causes the assisting toon to both use his basic AND deal bonus damage based on JML's max protection. 

While the underlying ability belongs to JML, the character dealing the damage is whatever character was actually called to assist.
