After being in an alliance government for a decent amount of time now, I have found myself wishing for changes similar to the following:
1) Enlarging the "About Alliance" and "Alliance Recruitment" edit boxes on the edit alliance page. It can be such a pain (especially with a text dragon) to scroll down and edit a specific portion of the alliance page in that tiny box. I am proposing either to enlarge it or make a button to go to a more complete editor on a different page.
2) The ability to create custom alliance ranks with custom privileges. A game that has a good version of this is OGame. Every alliance is run differently and I would think some alliances would like to be able to have better control over who can take the alliance over (Heir), who has bank privileges, who has tax privileges, and who can manage members.
3) A mail system for government officials to write a message that gets sent out to the whole alliance membership. I know that there is an announcement section to the alliance and that it notifies members when a new announcement has been posted. In my experience though, the announcement page is easily overlooked.
4) The ability to tax nations differently and to tax resources differently. Being able to say that nation a is taxed at x amount while nation b is taxed at y amount would make it easier for alliances to implement optional funding programs for groups of nations within an alliance. For an example, if 10 nations agreed to be taxed at 80% so that each day the total amount taxed from them is used to fund one of their cities. Also, if the alliance bank has a significant amount of x resource but is low on resource y, it will be able to set a higher tax rate on the resource(s) it needs.
Those are my proposals and I hope that they will be considered and even altered in ways to make the game better. Thanks for reading and have a great day!
