I'm mostly concerned on whether or not it will be in Injustice 2 for that daunting gear system.
Dragomier - make sure you let them know how important it is for you
I really wish some of these companies had unprotected DM's so I didn't have to hammer it out to them in 140 characters or less per tweet. I could always get at them on Facebook couldn't I?
There's not much point in contacting the generic company routes, you'll get better results from speaking to individual people. If you do a twitter search for injustice 2 and then hit 'people' you'll get a list of people who mention injustice 2 in their profiles. Some will just be big fans of the game, but others will be people who are on the development team.
