GvG has been on life support since 2015. Less than 1 in 20 active players played it then, and that was when it actually was playable on mobile with the Puffin (I think that was the name of it) browser. Not to mention that it was about the only thing to do outside the main city. I'm guessing that the revenue it generates has been outpaced by the cost of maintaining it. Years ago it was probably a prime place to spend Diamonds by healing troops. However, with the massive power creep, the hyper-leveling of GBs, and the relatively meaningless defense stats, I doubt anyone is spending many Diamonds to heal troops there anymore. It is sad, mostly because it was part of the original vision for the game, which has gone by the wayside since Anwar (the original designer) passed away.
