Just needs a clan/guild area or way to encorporate others. Also multiple set up decks so we can have different builds ready for the defense challenge or in general. Also only main bug that seems to happen, is when a new update comes and I install, sometimes I cannot play for a day or 2. The app will prompt me to update it when I open yet in the store it shows i updated it recently. It does not happen every update. But 1 every 3 or 4 I'd say.
