I agree! I would love more options, perhaps more masteries in the future, or special unlocks for raising your player level. Perhaps do a starcraft approach of achievements such as playing a certain number of games as a specific faction, or winning a certain number of 1v1, 2v2, 3v3 and so on… I also would like new statues, perhaps they could add chess pieces as a callback to the AoE2 intro.
We definitely need more color options, their premade colors are unbearable and hardly work well together.
Also I think it would be awesome if these banners showed up literally anywhere in game besides from the loading menu like it would be dope if it were flying atop your TC or if like 1 out of every 10 military units was automatically designated a bannerman… missed opportunities, hopefully they’ll add more in the future.
