Returned to this game after time away from it due to circumstances. This game was my favorite game by far for my phone. I had been playing it easily for two years or more. Now it seems that all nearly all characters in game are immune to damage to the point where even lower powered groups can wipe out higher powered characters. There seems to be next to no way without spending real money on characters when they're available to beat this notion just to have a chance at victory. Poor choices.
