You've certainly got a point.

That does sound like a good idea. I think the rule, that no one with less than 50 VP could participate in a battle, would still apply and so no new player could accidentally make themselves ill? The current configuration takes for granted, that every tribe has experienced players in the leadership, who will tell their newcomers what to do. If a new tribe lacks those more experienced players, needless problems seem to arise.

Likewise I have just noted, that one of the main reasons automatic acceptance of new members to a tribe is problematic, is that you may get zombies standing around doing nothing and costing money. But exactly how would you suggest to solve this issue? Simply not paying new members to a tribe, after all is no option, active new members of a tribe badly need pay to build their villages.

Both of your suggestions would require reprogramming the game by the admins. It is therefore not really something the council of warriors can decide on.

Perhaps this thread might be moved to the optimization board?
