I have done the math and, as orc, should have approximately 15k total offense to grab fat faeries.
this is no small feat. by pumping my army instead of exploring, I will build 15k offense (37.5opa), so when I attack, I can get the army AND the land in one fell swoop.
The real question is what do I sacrifice in defense. How much total offense/defense are the attackers/explorers going to be having oop??
