Abuse of wheat gathering by making new chars
Step 1) create new char
Step 2) gather wheat on the char
Step 3) trade wheat over to a friend on the main
Step 4) profit
This tactic allows to get wheat pretty much infinitely- allowing people to rush through ranks and basically invalidating cities that have fertile fields as a resource.
Suggestion: remove wheat altogether from tutorial and replace food with cooked meat players get by killing wolves/bears
also, remove the field wheat and field cotton from vale of shadows. seeing them and clicking them to be told to "go away, you are too OP", is annoying...
