1) Seperate CTS from DH
2) Cut down IAP prices or at least make it actually worthy (instead of feeling worthy)
3) Unlimited Contract Hunts, less grinding
4) More skippable ads. No one cares about them.
5) Make IAPs cosmetics-only for PvP content (if any)
6) Free-to-play players first. Make everything available for free and as humanely as possible to grind for.
It's your main source of income and you need lots of them to stay in your game.
7) See what's so good in DH2014. Really
8) PC port, via Facebook.
I do get a lot of beef for this game, but writing this means I still have one single drop of hope for this game. It's broken af, and I don't mind if they basically turn it into DH2014 HD.
