It gets old really fast. All it does is force you to drag your units back to the start after each battle so you can heal before your heavily damaged units draw more fire. They're trying to ape the mechanics of a crappy lane game when with only marginally more control afforded to the player they could have a reasonably amusing RTS. It doesn't help that the control responsiveness in these unity web player monstrosities is almost always utterly wretched.
