hey man - wanted to see if you have any advice about combat since your ratio is so damn good. are you usually a spammer or a stacker? both? 

I generally like to 10 stack. I place high range ships up top to guarantee first hit because everyone is spamming nowadays. Then I place flankers at my bottom 5-6 stacks. Pretty much always win on attack on aggressive. Hard to defend since everyone attacks on careful/normal, but i usually lose 1 or on occasion 2 colonies.
