The suggestion that attack morale is somehow causing vet players to leave is laughable. People stop playing mostly for one reason. The game is pay to win. If you have ever played a world with a literal millionaire you will know what it is like to see nukes you catch and wipe be back to full nukes in a matter of hours, repeatedly. That is why there are so many gold farmers, and so few players. People see that it is pay to win, realize they can't compete without spending a ton of cash, or farming a bunch of gold, and leave the game. Nobody is going to come back to the game for a new mode so long as the core mechanic is still spending real money. The design team has killed this game by making it more pay to win than a strategy game. People started playing because they wanted to play a competitive strategy game. When they found out the real competition was the size of their wallet, a lot of people decided it wasn't for them.
