Halfway through the game the difficulty increased to the point where, in addition to not positioning your troops anywhere stupid, you need to rely on luck to complete the missions. Don't waste your time on this game.
I love the game play. It is unique, yet familiar. I do have one gripe. The rate at which new buildings get unlocked is too slow. I feel like I'm grinding for experience because of the slow rate of progression - but for no reason since your heroes do not carry over from shard to shard.
