Elf may be overpopulated but victory in wars/arena/pvp can be won by which ever faction is the most organized. I know mc has the talent to beat elf in every way if they become organized. Good expert skill or bad expert skills.
I think it would be cool for each guild (upon reaching a certain lvl) to be able to make a guild hall. The guild hall could add more features that allow player customization such as a flag with tour guild emblem on it. Another feature could be creating a sparring arena in the guild hall that would allow you to fight members of your guild. (perferrably without arena tickets) Just something I've been thinking about and thought I'd share.
