I agree with point 1, 3 and 4. but I feel like they can have skins for units in the game for money, aslong as you can earn them for free rather easy as well by playing games and getting aoe points from them to buy the skins with.(itd be good for the financial state of the game in the long run, and will motivate them to keep releasing patches like league of legends)
the moment the meta becomes stale and the game doesnt get updated, people will start leaving, it’s what happens to most rts games. so they definitely need to think in the long term with this game.
i disagree with point 2. cards was a horrible feature, and made games imbalanced from the get go. I want an even playing field for aoe4, any tactical choice should be made in the game itself, not outside.
