ok with the army
if your attacking someone and you lose YOU CAN NOT LOSE ANY MONEY
if your being attacked and you have money depending on how much decides what you lose
sorry bout this urmom but i'm gonna have to use you as an example once again
when i attacked urmom when he had 900+ minerals i was gaining 20-40 per attack
(attack turns is a factor in gaining money if you use a little you wont have a high chance of getting money at all)
when i attacked someone with like 10 or 20 minerals they gave 0-1
use 15 turns and attack someone that has money and youl be good (try for people over 100 minerals lol no one rich has over 10 units for some reason)
to know how much money a target has find there posts and check the mineral count, or buy a few spys youl see alot of the peoples money besides people with sentrys them you wont know
but yea i dont understand why everyone with an army size of 11+ has like no money and everyone with an army size of 10 has 100-600 my army to big to attack them

well i hope my info helps you if you understand what i've typed
