Alliance Ad Idea
The little thing at the top of chat that rotates the message that says something like One account per device, or Patience is appreciated could be used of more than just this.
I think that they could use this for alliance ads. Each alliances vices/leader could pay a certain amount of coins to get their ad there. It would be a two line ad, and if someone clicked on it it would expand to a 9 - 12 line ad. Many alliances would advertise, so to make this work when a user logs into chat they would be randomly (or systematically) have one of the ads appear.
Just an idea, that probably won't work, but it's there.
