just one more thing

people attack for a few reasons:
1. A net gain in resources (self explanatory)
2. D-bashjng for TD (which I personally don't like)
3. Revenge (or avenge an alliance mate) you hitting them (as in you hit them and pissed them off)
4. A war (again probably D-bashing for the TD of the war)
5. Sat crashing because
a) net profit in DF
b) to cripple your mines until you get back on.
Well, You can only protect against 1 and 5 by hiding fleet and resources in FSing, build fewer sats and such.
For the others, just build LESS defense so they don't want to get the TD.
We don't need more Defense structures IMO because all it will do is make some people make more of them and then become dissatisfied with the structure and the structure can not be overpowered or else everyone besides miners/turtles will think it is unfair.
So -1 on this.
