Not every guild has that problem, but again thats the point of the mode. The challenge is to get the guild organized and to be strategic.
The point of being in a guild is being in a team. These are the people you will be playing with, working with, talking to. If they don’t communicate, then they aren’t doing anything for the guild anyways.
People want training wheels and changes for anything thats even remotely a challenge. War is a team based activity. A guild should not be able to win because 2 or 3 people can control what everyone else does. Just like any other team activity, you perform well or you don’t based on your teamwork.
Get yourself a solid leadership core, then replace people one by one until you have a strong team.
