There seems to be close to no real new "content", mostly just another artificial rewarding system added. Still the same old levels without any additions worth mentioning. Only now you're adding some more "sugar" to the "cr+heat-mix", to make it more "addictive".
Yes, the story & the atmosphere might be nice... That would have made the game more fun from the beginning and I'm sure new players will like it a lot... but I think for most players it's just too late for something like that now. It might do the job for a little while. But I hope you're working on new fun things to do. Not just new "useless" rewards to get for doing the same old stuff over and over again.
Maybe wait out with complaints for when the system actually goes live on the live server? You (and neither me) still don't know what they might have in "shop" for us, from what i've read the current missions are only a part of what will be available after the release.
