Try freedom of speech instead! There should be no limit on the number of alliance messages per day. Consider running a country in, say, 10 messages a day! Its not realistic.
That would be an interesting thing to see it made. Sometimes 5 messages is not enough whenever you are trying to discuss important matters. When you have members not in same time zone.
I agree. See no reason to have a limit on # of alliance messages. When you have a leader and multiple generals able to send them it gets difficult if one uses 4/5 messages and then someone else needs to communicate something that may take 2-3 more messages.
