Farm beauty enhancements
The screenshots of the world of Ashes of Creation are beautiful. I am sure players will want to settle in the prettiest spots and establish lovely farms, blacksmith shops, pastures to breed the strongest warhorses, and so forth.
I would love it if the game allowed me to put up birdhouses, bird feeders, bird baths, feeding bowls to attract birds and small wildlife. Attracting cardinals, or parrots, or hawks to my homestead would be fun. If we are able to trap raccoons and small game, or enrich fishing ponds with rich vegetation, that might be cool as well.
A separate idea: I expect that each server will have a dedicated public forum. In L2, one member of my guild, RumPunch, posted a weekly news column discussing sieges, personalities, myths , player interviews (some fictional) and rumors.
