First off wiping Conq is pretty dumb imo, but thats par for ARK. However, for the love of everything that is Holy, DONT MAKE IT A 4 SERVER CLUSTER!!! How are you guys so dense to not see that you will have 25 alliances dominate the 25 cluster, then they will complain there is not PvP. OR keep the small cluster and cap tribes at 6 man. Will still have alliances, however it would be harder to organize (not a great option, but better than what you have come up with).
