To start the ball rolling, here are some minor bugs / annoyances that could be fixed in the next patch (0.16) that are persistent from previous versions:
1. The Legacy of Serraine ability does not give ANY horse (warhorse or other) to the shop in order for champions to be able to buy it
2. Higher-level champions end up asking for negative amounts of money, which makes them impossible to recruit
3. The 10% selling price for items in the shop - please make it higher, or at least moddable
Feel free to add more stuff and I will update the OP as needed 
Best regards, YS
