The new crafting system Is a grind and was just a way for the game to grab money off new players (who wont know about the old crafting system) under the guise of it being “More Convenient”. More than likely the crafting system was setup this way intentionally and they are likely not to change it or by much. There is much better ways to monetize money from their cash shop but since cosmetics are tied into loadout cards it’s very hard, seeing as you can just have outfits/cosmetics for mercs separate and have more things to sell overall.
This level of stubbornness is beyond me, I really don’t get it. My only theory on this Is they are simply taking advantage of how Gambling/RNG systems work neurologically on the minds of adolescents (here is a journal of gambling studies on google.scholar if you want to check out the abstract or more http://link.springer.com/article/10.1023/A:1021275130071) to insure a consistent revenue flow on newer players who have shown to be a younger audience. they don’t care about veteran players, apparently that is not where the money is, its from bringing in newer players as @N8o has brought up a very good point in how this many people completed this http://i.imgur.com/CjtoNn2.png
