The only way any of this makes sense
Ok so kabam still makes a decent amount of money each quarter (at least as of 08/16/17). So where does all the money go? Other than paying staff, it sure doesn't end up being spent on the game upkeep.
My guess is they are losing the marvel licensing deal within the next couple of years, forcing them to drastically increase the release of 6*s and other content way faster than it would have / should have been. Milking every last cent they can from people before the loss of the license and / or just completely implodes. Meanwhile gearing up for the next scam of a mobile game and starting the cycle all over again with a different franchise.
