This is just hearsay from other commenters but apparently Oni really hates Jean Grey, so being forced to develop content for her (based on the results of a patron poll Oni himself created), may be impacting how much development time content he is willing to devote to her. It may also explain why her character model is less show-accurate than Rogue's or Kitty's.Also not to mention that he took LITERALLY one year to finish one character art, WITHOUT any scene what so ever, you want some erotic scene? wait 6 more months, because guess what, the next 3 months its all gonna be bugfixes. look at this game changelog, bugfix, more bugfix, and more bugfix. dont get me wrong the game is good, but the new content took WAY too long for the wait.
Again though, this is just word-of-mouth rumor. If Oni tells me I'm talking out of my ass when it comes to Jean Grey than I'll apologize and make a retraction.
