About my idea of "Lineages" in World of Warcraft, one thing too is a there could be a bank tab for them in the game. That way, players could put things in there for other characters they are not using. Then when they are on other characters they could access the vault.

Something else I think that would help world of warcraft is if they supported Gnutella. For example, instead of having everyone download the game from their servers they could have people download it a server closer to the game. Then it would make save bandwith and improve latency.

Another idea is that I think they should have a weaving profession. That way they could make cloth out of plants. Also they could make baskets. Perhaps even backpacks.

Another thought is perhaps the guilds could have apartment buildings. For example, in cities, or near them. Then each "lineage" could have their own apartment. They could store things in them. Have people over, etc.
