seems like most your issue is just what clans are, theyre a pvp feature focused around infamy and capturing islands
what you want already exists in the party feature, small groups that stop you from hitting eachother, i think you should just join one of the many discord servers if youre looking for people to play with
also pvp is literally the only thing giving this game some sense of replayability so asking vetex not to focus on pvp doesnt make much sense, its the only way he can make the game more replayable without reworking or adding features
