Thanks, just started playing.
The first thing I'm noticing is that coercion seems to have been buffed, which is fine but it's created a bit of a trap for new players. Currently to get the most of one thing you have to set it to ~70-75% (depending on your buildings) of what you want and then split the remainder between the other two. Since it also reduces happiness but the coercion amount (up to 50% now, scaling up rapidly at the high end) someone new to the game could really hurt themselves while thinking that they were focusing on one type of production.
Perhaps the wheel could be changed to emphasize how bad it is at the extremes now? Maybe instead of the blue/orange/green colours showing the different types of production it could be green in the center and changing more towards red as coercion increases?
Edit: Or maybe even change it to three bars that go from 0 to whatever the maximum amount of production for that type is, so that a player adjusting one could see how the other two drop extemely quickly to get that last few percent out of one type?
ie:
l----------
l----------
l----------
l---------------
l-------
l-------
l------------------
l
l
Edit 2: I don't know anything about coding a UI, but maybe the quickest fix would be to not allow you to select a spot on the wheel that would increase your coercion but not increase any of the three types of production.
Also, just to echo what others have said the only expansion content that seems to have made it in to the beta are the portraits for the new races.
