I have been playing for over 7 years now. I am quite active, and I have achieved a global ranking of 12.
I will no longer play unless the developers are able to make the new UI as simple as possible. This game is all about planning and strategy. Bells and whistles and fancy graphics do absolutely nothing for gameplay. Nothing.
Provide a way to use the "Pin" mode in the new UI and it might be salvageable. As it is the larger maps, which I and many prefer, are absolutely unplayable.
So, simplify simplify simplify! Your dedicated userbase could care less about graphics. All we care about is reliability and an ability to see things clearly, especially on the larger maps.
