Interesting comments by all. My own take is that whilst there are deffinate disadvantages to the mega guilds there are also options for smaller groups it just takes more work and better communication to handle mutliple guilds under one alliance banner ... however its not impossible as games like Eve have shown us. It is not a game killer, all it means is that the map will end up being split into alliance held territories with small guilds having to pay tributes and provides ships when needed in exchange for land.
