Suggestion
I think there is a problem with the rule of the game. We know that being able to attack other players depends on their protection periods and the population differences between players. Putting proctection days aside ( 'cause it's normal in every war game), I would like to talk about Population Difference. There is players entering this game just some days after I came in. They are not active or develop slowly whereas I have developed much faster than them. So now the population difference between my outposts & theirs is great. And the subsequence is that I can't raid/attack them.
So now you can see the Unfairness in this situation? I can't attack others 'cause I develop much faster than them? I hardly can attack anyone at the moment just because they develop too slowly or they are not online anymore ?
I recommend that you guys should change the rules in order to make the game fairer. Firstly, I think, you should allow I & any other players to attack players who is not online for 15 days or so because when someone not entering the game for 15 days, surely they will rarely come in again. You can also create Vacation Mode for players who are still interested in the game but they are too busy for some time (e.g: illness, going on holiday,...)
Secondly, you should reduce the margin of population difference. It's unfair that a player can't attack others just because he is much stronger. In this situation, you can allow him to raid resources but not to destroy their outposts. In fact, players can prevent losing resources if they upgrade Evaders. If I attack a player who is much weaker than me, he can still protect his resources. And if he don't upgrade Evaders, then he deserves to lose resources. That's the Fairness.
That's what I want to ask of you. Looking forward to your reply.
