I reviewed the updated Declare War feature here (1). The main problem with wars is that it's almost impossible to find an active one that you can help in. Manually searching your news feeds will yield this almost 99% of the time. It a frustrating process for many.
You can use the Event Scanner by Team Spockholm and select the "war" tab to lessen the load of scrolling through the news feeds (1). The same problem of being too late will persist.
The Operation War Hunter is a better tool to use because it only scans for active wars(1). The problem is not many of those exist and you often find you're mafia member is losing as they never asked for help.
The main reason the majority of wars are finished within seconds and you can't find one to help in is because there are automated scripts that scan for war posts and perform the action for you. This creates a problem for those players who want to manually help. There is a way to bypass this but it takes a little handy work. If you use scripts, the Link-a-Nator now provides your static "War Help" link. Check the "War help link" box and click on the "Generate General Links" box.
If you don't want to use the Link-a-Nator, you can still get your link by finding one of your old war help posts and copy the link from that.
Now that you have your link, the key is NOT to generate a request when you declare war on somebody. Close out the Get Help popup.
Now it's up to you to select the friends you want to help. It's best to declare war on players with less than 501 mafia as there will be some delay. If you're in an active chat room or group, this method is ideal. Eike introduced me to the concept of War Groups. They are secret and have a small number of participants. I was able to join the one below to see how it works.
The rules are simple and every member in the group can easily get their 5 war assists in a day without all the hassles of trying to find them in the news feeds. Anybody can start their own war help group to easily beat the bots at their own game.
