You have chosen war with a god!
With all of the uncertainty until just recently about WB and NRS. The push for another MK instead of Inj. We may not be seeing any WB guests this go around because of all of that going on behind the scenes. It's probably easier at this point just to get licensing for characters instead of risk putting in WB assets just to have had NRS get sold off mid development.lolwut? WB has plenty of femme icons that could step in here. Sarah Connor and Harley being two obvious examples, but honestly if you don't think Xena the fucking warrior princess and Buffy the Vampire slayer are influential pop culture icons that are worthy of a guest slot, then to put it generously, you need to widen your scope.
