This is just a idea, but what if you could watch the battle after you attack? Then you could see the cool effects of attack/defense pots in action. Just imagine the possibilities.
Try some other game that isn't losing revenue due to lack of innovation. Not saying this game isn't fun because it is, but if you want that then this just isn't the game for you.
People would watch a couple of 'select all' attk against a full def and then never watch it again. Even the animations on battle chess got boring after a while
People already complain about having to manually unload. Imagine replacing the simple text battle notices with a short animation or image PER tap. You would probably love it for about 2 mins.
