Good game but few problems

Good game. Ive been waiting and looking for a game like this where you fight with a character and spawn your own troops. The only things I can is bad about the are that its hard to get the gems to upgrade stuff, some of the enemys that block attacks dont take damage when their shields are down or when you hit them from behind and the A.I. Is horrible as the ground troops attack one target and huddle around them ignoring every other enemy.
