You can still get lucky and unlucky streaks- just with the lucky streak you need to pay a few m extra. I have a feeling that the new way is simply better for just about everyone; tomorrow I will try to keep track of the heroes I buy and spirits I get to come up with how many more spirits we get at the cost of how many credits.

Also, could we get a way to dismiss heroes? Admittedly at one point I tried to recruit everybody... think I have a few hundred white cards lol.
