This new change for 5 AC per day will kill a lot of things. 
1st - players like me will never have the change to lower the gap between old players and us. Up to now for example a strong player may not have the time to farm but lets say I do, I can do 50-100 AC and to collect some energy. Now when we have equal number of AC no chance. 
2nd - how people will tank battles without farm of energy ?
3rd -what we do with all that food now.
4th - no market of weapons anymore. 
Game will be p2w because people will need to buy tons of energy to do good battles.
