I've started to play this game with lots of def units and they when we were at peace with lots of alliances I just sent lots of them to some random cities to sacrifice since I was in need of farm space for offensive units.
And before anyone points out I have lost swords and archers in attack - ALL of these have been while farming, I even have a badge for it, sometimes my mistake, sometimes i think a lagging error and once an honest fail when i didnt know better while strengthening !!
Biremes where lost when supporting a colony ship that got sniped as I didnt have many lightships and hoped I could take some heat off the CS ina tight harbour, but failed - nothing ventured, nothing gained !!
After the last week of fighting I made it back into the top 3 pages of bp rankings! Cost me a few cities, and unfortunately this time it's dbp that put me there, but figured this wall was worth posting.
