A genuine question:
How hard would it be for the developers to provide a maximally simplified UI within the new client? That is, use pins instead of graphics for units, at the very least. Disable the superfluous layers.
This is a game that is not only about planning and strategy, but also about fine-grained activity at times. The new client simply does not allow the latter, and makes the former more annoying than it is worth.
So, again, how possible will it be to provide a radically streamlined option within the standard client?
