The only complaint I have is that using the "store all" option at the storehouse will also place inside your newly forged equipment. For the rest. it's a good and enjoyable game!
Maybe it wouldn't be a bad idea to make all invasions cost a much larger amount of troops instead of gold. This way having a massive amount of power would be the norm, and you will still get benefit to your economy.
Locking Frontline is an huge mistake in my opinion. Trying to get more money and all is right, but this way they are just going to lose playerbase and have buyers with less competitors. Hope they know what they are doing.
Also, as a side note, I was looking for buying this game, but the presence of several bugs, including progression lost and disconnects (infos read from Verdun Forum, not from this Kong version), and also a continual change of game features, like changing Mortar's CD and such, restrained me from purchase. Maybe the game will get better and better in the future, I hope so. Is not a matter of cost, I'm just unsure the final product is something I'm going to enjoy.

Good game i liked it, but i think you have made Selena a bit too powerful with all those healing/resurrect effects. I find really harder to play without her.
