Rotating maps are enjoyed by a large amount of players in this game, if anything I'd be surprised if we don't see it more frequently. I love it and don't understand any of your complaints; in fact you're literally the only person I've ever heard complain about rotating maps. Don't know what to do because it changes between 4 maps? That's nonsense. Perhaps you need to play more? Learn all the maps in the rotation. It's not rocket science.
