Hello everybody!
I would like to suggest that in order to build pirate fortress you would have to have higher level town hall. Around lv. 10 or higher.
This would in my opinion make piracy game a lot more exciting since you could not simply place around lv1 colony and immediately raid people. You would actually need to develop it first. This would also mean that other people could actually stop you - or at least have a fighting chance by pillaging it and blockading port.
I know what you will be saying: but you can warp a town with ambrosia. yes you can and you still could. but at least people would have to spend real life money to do it. so this is also good change for developers.
I also don't believe that it would be a hard thing to technically implement since there already exist buildings that have town hall level requirements (Shrine and Dockyard)
What do you think? any suggestions or counterarguments?
