Not to mention that if you don't need mines, any amount spent on them is a waste. While if you need them, not spending enough to do the job right is a bad thing. I am not going to argue that mines are neccesary Fyron. All I am saying is that if you decide they are, don't hedge your bet by doing them halfway. Do them right, or don't do them. UNLESS you need them and the the critcal issue is a lack of time or lack of resources. If that is the case do smaller mines, or somehting else entirely. That's why I say use the biggest mines you can afford that will be built by the time you need them.
