...completely useless. It doesn't matter if your army is worth 10, 50 or 100 million resources, there will always be players that has stronger army and will destroy you anytime they want even if it's not worth it for them to do so - just like player govinda71 destroyed mine today.
I would have to spend a whole month of my current resources production to create this army again. I am not going to do that. Honestly the only reason I had an army at all is because when the DWD token was released everything was really cheap if it was paid with the DWD tokens.
The DWD prices were just too good so they changed them and currently I feel it's better to not use them. There will be staking of DWD tokens in the future so I think it does make sense to wait for it. Waiting is still better than buying an army with them and having it destroyed just like that. I made a post about this previously, but nothing really changed. It's an early access game so even this problem will be resolved someday - maybe!
In short, if you are not going to buy or create the biggest army in the game then just don't do it all.
