First of all, with this thread i'm speaking as a player, not a moderator. This is a thread that has become suggestions and ways to improve the game from a player perspective. (Well mostly, some of you seem to just be negative in general haha)
200 member tribe limit is easily the biggest hindrance to this game. Tackling that with a revamped tribe skill system can help quite a bit. As with most games, you bring out new features, as the public market dives into the new feature, data and feedback should be collected and used to make modifications to the feature or system to improve it further. While this isn't something that can change overnight, it should (and is) be looked into for ways to go about improving the system currently in place. I feel once they implement a revamp with the tribal skills system they can then tackle additional problems. I truly feel the tribe limit is the biggest obstacle right now. Maybe if the servers were much more populated 200 wouldn't be an issue, however in my opinion, this is the biggest currently.
P.S. 200 tribe limit on a smaller poplation server only allows a handful of tribes to be successful as everyone flocks to anywhere from 2-5 main tribes, and the world just rides it out from there. With more smaller tribes things can easily take a turn with more tribes having an influence on the shaping of a world.
This may have been ranty but, expresses my feelings on the matter.
