ok healers are just plain stupid sometimes, if they can heal all enemies on the map including tough guys to 100% health at least introduce target priority
Another update which would be very useful is a grayed out timer before you can call the next wave, the number of times I called them late due to a distraction at the end...
Only about half way through but there really doesn't seem much point to archers so far, perhaps if they had a major bonus against mobs of flyers? but yeah great game
