I love this game, runs on my iPhone 5 like a dream, even with 100+ bots. But I would like to see something like water, which your scouts/hornets can pass but land units can’t. And maybe a command bot, which is a bot that has a aura that will make defense bots fight better, and it will allow you to command bots. You would click on the command bot, and a pop up command screen will show, then you click “rally” and it will make all defense units in the aura come to the command bot. You can then click a area and they (with the defense bots) go there. And to un-rally, you click on the bot and click the “rally” pop up again.
This is just a idea to make the game slightly more strategic, because I commonly want my scouts to head-off a group of bugs, but then they scatter and don’t even fight.
