ton of great tools, especially the farms search (1: on the left select World 2.com under America. 2: then click Farms search 3: then type in the corrdinates of the village you are attacking from. 3: then select the slowest unit you are attacking with 4: then type in the maximum time you wish to travel 5: then type in the maximum size of village you are willing to attack. 6: then hit the button "Farms search" 7: it will build a list of nearby villages. The ones with grey dots have shown no population growth for 7 days. You should probably scout it first.)
On this site there is also troop comparison page, which can be useful.
A bit confusing to use at first. But you will have to download it and install it. Then change a language file from english.lng to custom.lng in its directory for it to be in english. Its a nice program tho.
A great little combat simulator, includes hero, wall, palace. Everything you need for an accurate battle simulation... Tho, im not sure its result is actually 100% accurate.
