Wbs, I have another game I play, while it dosnt have the glitches this one does, it is quite demanding on the device. I have an iPhone 5s and an iPad mini, original that I have it on( yes I have multiple games there too) the only way I can open it on the 5s is to restart the device each time. The mini is dog slow, but eventually it will open. As the games offer more features and events, they become more demanding on the device. I have a mini on an iPad 2 and would find it unplayable in sup. I can still collect, and do basic things, slowly, but trying to deploy in FL, or attack in wd at the rates I olay those events, it would not be possible. I Don't think I could do 25 percent of the number I can on the newer devices.
