I mean, read the actual description of the EE version: does a game that requires an on-screen button to toggle between scrolling and selecting sound like something that's a perfect fit?
Does requiring someone to touch part(s) of the screen in a touch-driven interface to toggle grid selection sound any worse than having to mouse to the edges of the screen to toggle movement in a mouse-driven interface?
They say nothing that the button toggle is required for selecting either, just that it lets you draw boxes, which you don't have to do all the time in the game, you can likely just as easily tap the portraits or enemies directly:
The camera has been fully optimized for iPad and works in the way players expect. They can pinch to zoom their viewpoint in and out, and a simple drag of the finger moves the camera anywhere around the map. A button toggle locks the camera and enables drag selection boxes, making it easy to select multiple enemies in hairy combat situations. "
In fact, they actually say "the camera works in the way players expect," and "making it easy to select multiple enemies."
I imagine the controls will work well for those accustomed to them, and for those not, like any new control scheme, will just take a little time to master.
