@Highway don't know how the update is gonna play but when we gonna release update add this mechanic too - clan vs clan and not 1 clan vs 6 clans. Ultimately at the end if there are no enemies the server is gonna go dead what's use of making rex and not using it to fight enemies?.
Make it clan vs clan , if one clan attack other clan buildings in attack phase only the defenders of that particular clan members can attack or kill the attacker so this benefits both attacker and defender to improve their clan rather than depending on ally to protect. This makes every clan leader to take indipendent decisions rather than going all together and eliminate those go who against.
PvP all clans is available in protection phase and clan vs clan active in attack phase which gives balance to both while having the existing attack / drain rate. This makes sense for any clan to fight alone to prove its strength. Now PPL who gonna hate this idea is a weaker clan and depends on ally.
