You've already lost the fanbase on the strategy game the absolutely best direction you can go right now is to add a new last stand mode. It just makes more sense that the Last stand should be a priority to lure people back into the game. I am however happy to see that you added new skirmish modes to prevent the game from becoming monotonous, although it makes no sense at all to add annihilation when the powercore mode is exactly the same but with turrets... Unless you intend to add ffa and team-ffa modes aswell. The obvious choice here should have been victory points or some kind of objective mode, instead of the same thing in different wrapping.
If you still can't get the fanbase back then you must improve the AI as soon as possible, it sucks and everyone knows it. Not only does it play as a useless opponent it has no random option, why is that? We can't choose to play against a random race and the doctrine options are premade...
The Customizable skins was a good addition, finally we can color our champions aswell, however the champion skins doesn't follow the same pattern as the units which makes the chapters/craftworlds incohesive. This should be fixed, the worst example right now would the the classic macha skin that makes her primary color grey no matter what.
