Do you have a video about knowing when to use speed ups in the correct manner? I use up too much at one time and waste them on training my troops, etc. A good video could be for free to play players like myself, and show the best strategies. As, I don’t want to spend much on this game.
Can you help clarity the Army Carryting capacity please as you didn't mention it. Does this help with how much you can bring back when attacking another players city?
I wouldn't waste points on production of building resources they dont produce enough regardless of your building level or how many points you put in to be relevant.
