Playing JR as the Empire and the Rebels got Luke with their first side mission. He's totally dominated the campaign (along with Shyla, who seemingly can move across the board at will). Do folks think he's overpowered? The boardwars guys don't, which I find astonishing. They gave him a 2/5 for campaign.
Luke has a speed of 4. That's comparable to most heroes. But, he has heroic for two attacks in addition to his move. And it's a three die attack, as well. With built-in damage, pierce 3, and deflect, how is he not better than any ally in the game? He averages five damage per attack.
He's like a really good fifth hero on the board that attacks twice and suffers no strain for additional movement. Or, he moves 8 and attacks.
I hate him. I wish Vader had finished him off in Cloud City.
