well the rotation helped me in the first day to get to know the maps fast. If you play 2 maps for several hours youll get to know the maps alot faster as if you always switch between MANY maps.
So i do like it in the beginning but i guess it will be annoying in the future.
On the other hand at the moment im starting the game often again if the maps rotate again, so its clearly a reason for me to start the game more frequently, because there is anytime something new to explore :D
