I'm not seeing Luke being a power piece. No matter how many cool abilities or HP you stack on him, he's still a 12 point melee unit that can only attack once per turn (Heroic only states he can attack without using an action, not that he can break the "1 attack per turn" rule).
There is no 1 attack per turn rule. There is only one action containing attacks per activation rule.
Any number of attacks can be performed during an activation as long as your second action does not perform any attacks. You can perform any number of attacks from one action (also when you need to spend two actions to perform it), and any number of attacks from abilities that are not actions.
See for example here: https://community.fantasyflightgames.com/topic/227004-jedi-luke-heroic-and-attacks/
Luke Skywalker (Jedi Knight) can do an Attack action to perform an attack, then use Heroic to perform an attack. It is not breaking any rule. It is also working as intended.
