I suggest to have a closer look to this game from Guild versus Guild perspective. Inno says that Guild versus Guild will not be cut off (in capitals!). But with so many negotiations goods became a problem. Especially lower era goods if we ask ambitious, evolved guilds. Rogues can fight in any uniform, right ? Alcatraz produces soldiers in iron armor or robots without any problem - correct ? I say that Arc should be switched to lower ages (only to lower !), once per week, at our will. Of course, we should admit a limit, so let's say that only an Arc level 80 or higher. I'd like to know the opinions from official's side. Because players evolves faster than before (I remember the situation 5 years behind), they go through ages quickly than ever and even if they have an evolved Arc, this structure don't produce what a guild actually needs, in accordance with the plans adopted in Guild versus Guild section.
