One of the most popular pieces of feedback we've gotten is to limit the "cheese" factor of some of the challenges. The challenges that can be exploited through intentional draining and skill shot selection. While I personally found the exploitation of the rules very interesting, it makes things a little odd for those that don't know "the thing" as a player, and god help the viewers who definitely don't get it.
We're likely to switch to tightening up the challenges to be more direct with respect to the thing to do. The Aerosmith X multiplier challenge seemed to be the most positively accepted challenge.
So something like Tie Fighter MB can be a challenge, but we would force players to choose Leia, or some character where the skill shot won't help them advance the challenge.
For Super Jackpot on GB, the challenge would be to defeat both Scoleri brothers and collect the Super.
I think that will help give players the feeling that at least the know how to get the challenge, rather than feeling like they lost before the match even started because they didn't know the exploit.
