I'm the Imperial player in our games. The friend I play it with has a clear pattern now with every campaign: Take Diala, make a mad dash to get Dancing Weapon, proceed to make every round "Diala uses Dancing Weapon twice."
It's obviously a very good, useful card. It's just... dammit it's Every. Single. Game. I have no other issues with him or the ability except the knowledge that Diala will be doing it until she can't take any more strain. If it's supposed to be a saber throw, I don't recall off the top of my head what length of real time an action takes, but the visual I get is that she throws the saber, it comes back, and just immediately hurls it again.
I'd be interested in any strategies for countering it, etc.. I accept that we might be using it wrong but it seems like once she gets it, that's MOST of what she'll be doing for the rest of the campaign, so if there's a rule I'm overlooking, would be interested in that too.
