While quality of life improvements are fine your farming ideas ignore that this is a resource management game. Also older characters are available in many of the stores, and if characters were easier and quicker to obtain then why would anyone pay for characters?
You do get notifications for GAC, I even get ones to set defences and attack when I have already done both.
It also makes zero sense that on one hand you complain that "The game has become very labour and time intensive" yet you ask for more game modes. You can't have it both ways.
