Playing a 4v4 game on a huge water island map.
With the map being so huge and the distance to travel, it was an automatic Wonder loss. The opponents team built a wonder in the very corner the map, and 10 minutes to gather all your units and travel by water is not a lot of time. They did a fast imperial as my team were just starting to build an army. I would say increase the time to 20 minutes for a Wonder victory with very larger water maps.
