Morale worked fine in Tribal Wars, but you know what? This isn't TW, not to mention you can't have nearly the size army you can on TW.
If this was implemented on the world as the world first started, not many people would of came here period, and those that did wouldn't of gotten as large as they are realizing that it's pointless. This game already favors defensive, so why give them more advantage?
My next point is, they say they want the game to be more fair for others? The game is already fair, we all start at the same time our neighbors started, just some are better players, others have more time, and others got started in the right alliance, so why punish the people who did good, for the people that don't know the game?
My other point is, if they are just starting, close Alpha to new comers, let the people already there play, but they have newer worlds for the new comers, you've already put a 48 hour travel limit on the colony ship, but what makes the morale thing really unfair that, some of us that dominate have NOBODY near our size within a decent attacking distance, and due to the 48 hour cap travel limit, we can't go conquer in other oceans where the larger players are, so we have to get small ones to slowly expand outwards. Then to top it off say I did want to attack a player my size. I would have to travel nearly 20 something odd hours, which then that player can either completely stack his polis, or if he chooses, he can dodge, which is what any good player will do.
The morale was also a moronic idea due to the fact that we all have the exact same units, so why would one have a better morale? You already have given that to defensive side, with the wall, and/or tower being built.
