So I've been trying to learn how to do the most damage, and I was thinking that if you have two 5 man stacks attacking a 10 stack, it'll be good as the 5 stacks will be using their full damage, but then I realized that this gives the 10 stack more chances to attack with their less efficient, but still higher numbers.
So basically using the spreadsheet of the damage efficiencies for different armies:
two 5 stack = 6.0 x 2 = 12
One 10 stack = 7.8 x 2 = 15.6.
So the 10 stack will actually be doing more damage. Does this mean stacking even with worse damage efficiency is actually better or am I missing something here?
